Security Certificate Error While Opening Web-sites


A friend called me few days back and told me that he is getting “Security Certificate” Warnings while opening web-sites. Mostly when he opens some secure sites like online banking etc. There are three main reasons for such errors. In this post we will talk about the such errors, how they look on different browsers and how to fix them.


The Security Certificate Warning looks like as shown below for IE, Mozilla Firefox and Google Chrome. Click to enlarge the images.

Microsoft IE- There is a problem with this web siteย  Security Certificate

Mozilla Firefox – Secure Connection Failed

Google Chrome – The server’s Security Certificate is not yet valid


Security Certificate error in IE


Secure Connection failed in Mozilla Firefox


Security Certificate not valid error in google chrome

Lets see the reasons for such errors and what to do in such case.


The main reasons for such errors are:

  1. Your Computer’s date is set to a wrong value
  2. The Security Certificate has really expired
  3. The web-site is not trustable

Most common reason for such security certificate error is that the certificates are valid for a certain period of time, and if your computer’s date is set to other than the current date or correct date, there are high chances that you will get this warning. So the first thing to check when you receive such error is to check your computer’s date and time settings. If the date time keep re-setting again and again, then see this post on CMOS battery problem.


Now when you have set the date settings, you will most probably not see the this error again. But if you see the Security Certificate error, then either the certificate of the website has really expired as it had to be renewed from time to time, or the site is not trustable.

TIP: Never ever put your important login id or password on such pages if you see the Security certificate error.

  1. Actually the term used in this article “Security Certificate” warning is too generic, because there can be other types of errors\warnings related to security certificates as well. One of the most prominent ones being when a site is using a certificate belonging to some other site, leading the browser to believe that the site is not trustable, but it is indeed trustable. A common example here would be that uses a certificate belogning to So, in these cases there is no quick fix but one has to apply any factual knowledge or common sense to see whether it is ok to accept the certificate or not.

  2. Great information. I had forgotten that I’d been changing the system date for some software trials and hadn’t changed it back. Low and behold, my wife just called and said the computer wasn’t working. An hour later I found out what the problem was, found this post and fixed it. Good stuff, thanks!

  5. Hey, Kaspersky products (KAV and KIS) can cause this sometimes…You need to disable the “Encrypted Connection” checking under “Traffic Monitoring”…Works

  9. Thank you so much!!!! I just spent 3 hours on ms support website chasing my tail trying to figure out why I haven’t been able to log into messenger, and all websites were diplaying this error. Found your site and fixed on about 10 seconds!!!!

  10. This is FABULOUS — just helped my 60-year-old mother figure out how to change her date and time so that her gmail would work again. They had a power outage yesterday, which caused the date to go back to 2002. Thank you!!!

  11. Hello,
    yes your advice was helpful. But I’ve got a question related certificate error message, when it keeps telling you to accept it, although I’ve done it many times. My BIOS is alright. Just don’t have an appropriate certificate for the web-site.

    So now, do you know if I could change it, that I won’t have to “add an exception” all the time. Maybe I have to make changes somewhere in the settings?

    Thanks in advance!

    Be Blessed.. ๐Ÿ™‚

  19. Simple thing – wrong date – but I tried loads of things and a few websites before your answer just directed me to correct it

    Thanks very much.

  20. My son’s computer had a security certificate problem when using Google. The site was displayed in Dutch and when you would click on the link to sign-in, you’d get the security certificate warning (like the ones shown above). This happened in Opera, Firefox and IE. I used Spybot Search & Destroy which found a “Windows.Fraud” malware with 111 entries. But it wouldn’t remove this malware and gave an access error listing C:\WINDOWS\system32\drivers\etc\hosts. I went to this subfolder and deleted the file “hosts”. Then when I opened the browser and Google opened in English and I was able to click the link to sign-in. This worked in all 3 of the browsers. I re-ran Spybot and no malware was found.

    I’m pleased with my saavy computer chops for fixing this. But I can’t explained what was amiss. Perhaps someone out there can.

  21. Thankyou!

    I had been trying to sort this out for a while and i could never sort it.

    My date was in 2008′ instead of 09′ xD

    Thankyou so much ๐Ÿ™‚

  22. Thank you — inadvertantly reset my date last night while planning a schedule for 2010, without knowing the impact the reset would have on my security certificate expirations. I was sure I had been hacked, phished, defrauded, etc. After running my security software a couple of times, found your site via “security certificate error”, found the problem as you described. Don’t have to buy a new laptop yet, don’t have to slit my wrists. Feel a little bit more knowledgeable, though still pretty dumb. Looks like I’ve got a lot of company. Thanks again.

  23. Well Thanks a lot. I was not able to open website cos of date problems and your suggestion solved my problems. Keep it up

  24. Thankyou so much. I’ve had so many problems with this and it was the date all along. It’s 2010, but my computor was set to 2007. My wife can now spend again!!

  25. there’s more than just 3 possibilities.
    my mom got that Additional Guard Virus on her computer and now she can’t access google (automatically redirects to Google Canada which is kind of a pain) and the gmail certificate’s are expired.
    according to all scans i’ve gotten rid of the malware but some of the problems it caused still persist. like the certificates and her computer’s apparent love of maple leaves and hockey.

  26. my computer had an certificate error when im log in to my facebook,, i cannot log in can you help me to fix it,, please thanks

  27. Thanks a Lot!!!

  28. Hi,

    Thanks alot your information was really helpful, you are really great, i honestly appreciate your talent and kindness


    Many Thanks,


  29. My google certificate has actually expired and I constantly get pop ups stating that 443 uses an invalid certification with error code: sec_error_expired_issuer_certificate. My computer is set to the correct date and time. How can I either obtained an up-to-date goggle certificate or remove this error message?

  30. Thanks so much for the help. I have done a number of searches trying to find the cause of this problem including Microsoft’s website and not until I came across yours was i able to fix it!

  31. This worked for me …amazing ..thank you.. I had to call HP and they told me to contact Microsoft..I was going round and round in loop. This post helped me ..thank you so much

  32. Its really very nice. You people are doing really great job. Thanks a lot. I was getting very anger for this. But thanks to u. Hope you keep doing this good jobs.Take care

  33. Thanks a trillion times. You just made the problem solved. Great work. I appreciate. Love YOUUUUUUUUUUU !!!!!!!!!!!!!!!!!

  34. I am trying to find another solution. My date and time is correct and the problem still persists. Lvair could you please explain your solution…..I cannot find the option you are talking about……I am using Vista.

  35. thank you so much for the step by step solution that you published here. i spent over an hour trying to figure out whats wrong with my internet explorer and it was a date problem. cheer!

  36. My date is right and two government websites that I visit always show an error. I ignore the issue because I need these websites to pay bills and such.

  37. Hi,
    even i am suffering with the same problem which all u people faced.I am unable to open Gmail and orkut as its displaying the security certificate has can any one help me out.

  38. The date is not the issue for me. The certificate error started locking my access to my company sslvpn – I cannot find a solution. Tried adjusting firewall, certificate is accessible by other people just not me. I think it is something to do with WIE8 or W7 operating system. Any help would be much appreciated.

  39. pls check time first then do as i say friends
    check weather any file is there with name host
    delete that file
    restart computer
    it will work.

  40. hey!
    I got my pc formatted and didnt check the date (it was 22/07/2010). I installed Kaspersky anti-virus. Then I noticed the date was wrong, it should have been 21/07/2010.
    So, when I put the right date the anti-virus gives me an error: “Incorrect activation date”.
    What can I do to fix this?

    Thank s for any help =)

  41. yes yes yes!
    I got no more access to: gmail, google earth, google search and google image. I was redirected to a fake google, bullshit search engines … ect, and bad certificates.

    “C:\WINDOWS\system32\drivers\etc\hosts. I went to this subfolder and deleted the file โ€œhostsโ€. ”
    solved everything for me,

  42. Wow, I spent over an hour trying to find the problem…..Thank you so was my computer time, which was set at the year 2099. How that happen I have no clue but thanks again.

  43. Thank You! I’ve been having a hard time getting to all our usual websites since we moved & had to pull out the battery, in order for the computer to start. It was a real pain, & after trying it for most of the day, it’s finally working. All because of the stupid date!

  44. Thanks a bunch.
    You saved my son from being loosing his computer privileges.
    You were exactly right–it was the date. It was set to 2005.

  45. it doesn’t work for me…
    I’ve been trying to sign into hotmail for a week now and i still keep getting those messages. It’s not like hotmail’s not trustable right? and i don’t think that the certificate has expired. Help please?

  46. when i open this site its shown security error and blocks the contents an and later the complete site, the date in my machine is correct, pls advice me.


  48. This was so helpful, my mom’s computer wouldn’t go to any site. She, like most of us, pays bills online, but she couldn’t get to them b/c of the security certificates. The date was the problem, it was set for February 2001 not September 2010. I was racking my brain trying to figure it out, until I stumbled on this website and the help. I really appreciate it.


  49. Wow! That was really a great help. I didn’t expected that the system clock would be so bothersome if it is not correctly set. I even have resorted to installing another web browser just to have the same warning I’m getting from IE8. But now I can go to any website without the security certificate warning. Thank you for the help. I really needed that. ๐Ÿ™‚

  50. Dear Boss,

    Greetings.. this troubleshooter hint is very very excellent. Even if he is genious in IT, Small mistake make big problem.. I really appreciate for this hint…thanks a lott..

  51. Dear Goodness, You just saved me hours on this computer system. I needed to use it for class today and couldnt figure out it was just the time setting. Thanks!

  52. I have the same problen clock time and date are correct , this invaild ceetifacte thing only appear on my hotmail sign, does not come up on any other site,Grrr Ihave no idea on PC either onl use it to do my NVQ ;(
    Good to hear others problems have been sorted on here, i’m hoping

  53. LOLL told you i dont know anyting about PC’s, message just gone up with the wrong time, its 8.45am, i shall ask a friend to change date for me Luck i found this site Thanksssssssssss xxxxx

  54. Yeah so far so good but the problem is, if one have already a correct date and time and still facing the problem like the renewal of certificate then how to cope with this problem. How to get renew the security certificates.

    Thanks in advance.

  55. hello
    the date and time of my computer is right.but still when i open any websites ,IE security is asking wheather to allow to open or not to allow.if i click allow same thing is asking me again and again.if i click dont allow same problem is arising again and again.pls can any body solve my problem

  56. Hello there,
    I have the same problem, maybe because of the date & time error that make me get this error… I’m using norton go back and it does not adjust the time~… Any others way to prevent the certificate error pop out?

  57. seriously mate, thanks a billion for this, had this several times in several different places, so now i know.

    once again thankyou

  58. Right click internet explorer and go to its properties. select “content” tab and see certificate. Do whatever it ask you to do. Like select certificate or publisher.

    Second option is to double click internet explorer and when any internet page gets open, see “safety” tab on the marginal top right side of the page. where click security report.

    Hope so you cope with this problem. Mostly problem get resolved simply clicking one of these options.

    Even though if you have problems, email me.

  59. After struggling with various ‘solutions’ for a month, I discovered from one website the reason why I was getting ‘Certificate error’ from a trusted website. All I had to do was to go to Controll Panel, Add remove programs, Windows components, and update root certificates and Voila! everything turned out OK!

  60. i have another possible solution that helped me when, even after changing the date/time, i still had s.c. issues. i found the underlining problem somehow ended up being java script. perhaps uninstalling and reinstalling can fix it for you too.

  61. I helped a friend touble shoot such a problem and your information made it very simple to resolve. We knew that it was a trusted site and used it before (our bank amonst others) and checked the only other possibility – that of the clock. A technician had serviced the machine and somehow got the time setting wrong and we were not even aware that it had changed. Your information saved us a lot of time and frustration. MS help was no help at all. Their help information is not written by real users with real problems. It is based on wild assumtions that all else is correct reducing the value of the information they offer to zero for anything but the most basic problem and is genraly redundant.

  62. Oh, I feel like such a moron. Such a simple fix. I was going crazy trying to correct this problem and couldn’t figure it out for anything. Thanks a lot!

  63. Thank you so much for this simple fix!! Yesterday, I walked away from my home computer while on a secured site. I didn’t get back to it before it timed out. Next thing I know, I’m getting the Security Certificate error on select websites. Called one number I had for MSN – they said it was a virus and for only $169 they could fix it. Called a different number this morning and they didn’t think it was a virus but would only cost $69. I didn’t want to give them my credit card number so told them I’d get fixed locally. Then I did a search – and thank God I found the answer! I did notice yesterday that the time had changed, if only I had just changed it then I wouldn’t have worried about it all night. Thanks again! I will keep this website on my list of important sites to use as a resource.

  72. To work around this issue, install the Microsoft Windows Small Business Server 2003 (Windows SBS) self-signed certificate on the client computer.
    To do this, follow these steps:
    In Windows Internet Explorer, click Continue to this website. A red Address Bar and a certificate warning appear.
    Click the Certificate Error button to open the information window.
    Click View Certificates, and then click Install Certificate.
    On the warning message that appears, click Yes to install the certificate.

I re-set the date, but that didn’t work, and wasn’t off anyway. Then I discovered the same problem on another computer in our house. One lovely person (I think it was on this site, but I lost track of the many I consulted) suggested disconnecting the modem/wi-fi, waiting then re-connecting. Such a simple thing, but it WORKED! I am eternally grateful, and sending happy thoughts in your direction ๐Ÿ™‚

  103. Hey, so I just read all of your three tips on how to fixing it. My date and time is exactly the way it is suppose to be. In google chrome, I went to Twitter and it showed me that security certificate thingy. So I ignored it and went to the page lots of times. Then one day I got a message that says I cant go there anymore, it only says “Back” What do I do?

  104. Thank you guys! I think my computer needs a new CMOS battery because I put it to the right date and time before, then it went back to thinking it’s 2006. Always wondered why I got those notices until now. ๐Ÿ™‚

  105. thanx a lot……i just put the exact date n time 2 my computer…..n now there is no error…. god bless u abhisek. u r jus ausome. thanx

  106. Recently (last two months) getting a rash of Site Security Certificate not trusted on WIDOWS XP on both Internet Explorer 7 and Google Chrome as browsers. My clock and date are fine. I use Kaspersky internet security. Same happens on my other Computer running XP with Norton Security. Not all secure sites show this warning so WHY ?
    Is this a latest problem with XP ?
    Is there a fix out there ? Does Microsoft know or care? The websites including traders seem to think its the users problem and not theirs but could be losing trade. Seemingly they have no concern when their certificate is reported as ‘not trusted’

  107. When I put this problem to Microsoft THE WANT TO CHARGE ME ยฃ31 for an answer to something that may be their problem

  108. i have problem with my batteries so my time keeps on resetting. i got tired of changing them every time. so i give up. but now that problem on certificate bugs me off. what is my option? any help?

  109. When I login to from chrome on new toshiba laptop it shows warning “The site uses SSL, but Google Chrome has detected insecure content on the page. Be careful if youโ€™re entering sensitive information on this page. Insecure content can provide a loophole for someone to change the look of the page.” with a lock and a yellow triangle over it.

    When I login with another laptop of HCL there is no problem, green lock with full security is shown.

    For both my chrome setting is similar.

    How to solve this as I am afraid to book any tickets fromtoshiba laptop.

  110. What if:
    A) The date is accurate
    B) The site is trustable
    C) The security certificate is up-to-date?
    What then? I get security certificate errors at most websites and none of the above applies to my situation…

  111. Thanks a lot buddy….it really helped…
    I was facing this issue for quite a time…my laptop date and time were set wrongly ๐Ÿ™‚
    Ur expert advice rely helped ๐Ÿ™‚

  112. Hey my laptop’s date was changed so i chnged it. But even then I am not able to open any pics..there is a cross on every pic..can u please help me.


  113. Thanks. I thought that somebody is intercepting in my network until I saw you article. My date is set to 2002 and not 2012 that is why I am getting the cert error.

    Great fix. Thanks.

  114. Everyone reason 4 their problem was because of the date. But that isn’t the solution to my problem. Do anyone have other ideas that could help me rectify this situation? Thanks

  123. Hi,

    It really worked. Good job sir. I didn’t ever notice that my system’s date and time were running incorrect. After reading this article, i immediately fixed date and time and restarted the browser. Then it didn’t show any error. The certificate error was fixed successfully and now i can surf the net smoothly.

    Thanks a lot.

  127. HALLELUJAH!!! the date was wrong after my netbook came back from a repair shop. changing the date FIXED the problem!!! it took me 1 week, multiple VIRUS SCANS AND CLEAN UPS until I found your website and read about the DATE – this made immediate sense to me! and it worked setting the date 2 year further ahead – hahahhahaha, none of the many computer geeks that I asked could solve the problem

  128. I use five different computers, three, two using XP and one using Vista work okay, but two others using XP and Chrome both refuse to pass any HTTPS sites. This clearly shows it is something to do with the Chrome not agreeing with something. Chrome also crashes Flash on all machines but Adobe says it is the settings, not all are the same so Adobe, in my opinion, have a system that has errors!
