Security Certificate Error While Opening Web-sites

by Rohit Khurana on September 8, 2008



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 site  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.

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.

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!

Kamal February 3, 2009 at 8:45 pm

Thanks a lot Abhi. I was really struggling a lot due to this continuously coming errors on each page…. When I saw your post, the reason I got was due to the older date on my pc for my problem.

Really thank you my friend.

Warm regards,

Googleeyes February 8, 2009 at 4:20 am

Fantastic – my date was changed – we have several of these errors at work also. so i will trouble shoot them as well.


Lior Aviram February 24, 2009 at 6:52 am

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

Njdeh March 5, 2009 at 3:02 pm

Really thank you my friend ,It was from my computer date.

Rai-mon Nemar March 8, 2009 at 12:03 am

I really had to say thanks. I thought i was going to have to take my computer back because of this error then did just a little searching and came here. Now my life is better. Ok so it didn’t fix my life but it feels like it. thanks you’re the reason the interweb is better then newspapers. 🙂

Daisy April 3, 2009 at 6:52 am

Kate May 22, 2009 at 5:49 pm

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!!!

Lilit May 25, 2009 at 10:15 pm

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!

mike July 1, 2009 at 4:16 am

Also, sometimes this error can happen when the “www” is omitted from the url. Try adding a www if it is missing.

ashi July 8, 2009 at 10:04 pm

Bryan Pepper October 17, 2009 at 10:36 pm

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.

KB December 10, 2009 at 2:26 pm

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.

jimmy January 6, 2010 at 9:18 pm

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!!

Mr. Yuk January 11, 2010 at 12:43 am

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.

mitch February 2, 2010 at 3:59 pm

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?

Michelle February 16, 2010 at 1:41 am

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!

Rob June 23, 2010 at 1:42 am

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.

Lavanya July 10, 2010 at 9:50 am

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.

unknown July 15, 2010 at 10:05 pm

thank u

joyful516 July 20, 2010 at 2:00 am

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.

madhan July 21, 2010 at 10:24 pm

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.

Ana Silva July 22, 2010 at 2:51 am

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 =)

yann July 22, 2010 at 2:26 pm

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 “hosts”. ”
solved everything for me,

Angie August 7, 2010 at 6:18 am

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!

L.W. August 12, 2010 at 8:25 pm

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.

melissa August 12, 2010 at 10:32 pm

izhen August 13, 2010 at 5:58 pm

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?

Raja August 19, 2010 at 9:25 am

thanks man, it really did work…

when perez September 12, 2010 at 9:46 am sure did work! :))

Philip September 25, 2010 at 8:19 am

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.


Archie September 25, 2010 at 9:56 pm

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. 🙂

Hidayathull September 26, 2010 at 10:33 pm

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.

raffuidu November 6, 2010 at 2:42 am

XxMrXAng3lxX November 13, 2010 at 6:54 pm

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?

Mustafa December 2, 2010 at 5:09 pm

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

once again thankyou

shah khalid December 3, 2010 at 10:56 am

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.

JSTOM December 8, 2010 at 2:01 pm

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!

rahul December 12, 2010 at 2:41 am

thanx alot that works for me
keep up the good work

shah khalid December 14, 2010 at 9:58 am

@JSTOM……… 🙂 hahaha good work.
Don’t mess with guys.

Excellent information; correcting the date resolved the error message. Thank you!!

Jeff January 8, 2011 at 10:16 pm

awesome thanks. date was wrong haha

danny January 10, 2011 at 11:37 am

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.

Ross Terry January 22, 2011 at 8:57 pm

Worked a treat ! I must say I didnt expect a new computer running windows 7 to play up like that !

prahlad k January 22, 2011 at 11:33 pm

o thanx a lot i really forgot to set my pc date n time . thanx a lot for a usefull information .

Orlando February 11, 2011 at 5:56 am

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.

Terri February 17, 2011 at 10:19 am

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!

Rhonda March 2, 2011 at 9:12 pm

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.

This error pops up quit bit when I try to login to Facebook, my fix is close the browser and unplug the router and push the reset button. It’s a very annoying problem and Facebook is the only site where I get this error.

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.

Got this from Mircosoft Support website

Worked for me!

Bethe October 20, 2011 at 11:07 pm

Yesterday I spent hours on this problem. I was unable to log into ANY webpage that required you to sign in, in fact, the sign-in page would not come up at all. 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 🙂

I logged on one day and everything was fine and then the next day it went nuts and everything I did a security warning come up. Now that I learn it was the date I do remember looking at the date on my computer for something and I must have accidentally changed it at that time. Thanks for the info. It has made my computer life less stressful! 🙂

pzp1212 January 1, 2012 at 2:37 pm

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?

Derp January 2, 2012 at 12:47 pm

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. 🙂

TUBAL CAIN January 17, 2012 at 8:41 pm

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’

TUBAL CAIN January 17, 2012 at 9:13 pm

When I put this problem to Microsoft THE WANT TO CHARGE ME £31 for an answer to something that may be their problem

ICDogg February 16, 2012 at 11:29 pm

no help for me, unfortunately. The date is consistent and the certificates are fine, but I get the error anyway.

Dr Acharya February 18, 2012 at 10:32 am

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 you’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.

Josh February 23, 2012 at 4:14 am

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…

Chris March 1, 2013 at 4:27 am

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!
