How Do I Fix "Invalid Or Expired Security Certificate" Errors?

Nothing will send chills up your spine quite like going to your bank website or trying to sign in at PayPal and getting a big Invalid or Expired Security Certificate warning in your browser. The warning instantly informs you that This Connection is Untrusted. If you can’t trust the connection to your bank, what can you do. Before you slip into a state of panic, there are two fairly typical reasons for this error message occurring. One cause of Invalid or Expired Security Certificate errors is a problem with your computer. Another common cause of Invalid Security Certificate errors is a problem with the website address you typed into your browser.

One of the most common causes of an Invalid or Expired Security Certificate error is the clock on your computer being wrong for some reason. Website security certificates are issued to be valid within a given date range. Your web browser compares the date of the certificate to the date on your computer to verify the date falls in a valid range. If the date of the certificate is too far outside the date on the computer, your browser will give you an invalid security certificate error because the browser thinks something is wrong. The fix for this problem is to set your computer clock to the correct date and time. It may require a reboot before your browser will view the problem as corrected, but fixing the date on your clock fixes many of these errors.

The other common cause of invalid security certificate error messages is typing in the wrong website address in your browser. For some bank websites, there is a difference between typing https://bankofamerica.com and https://www.bankofamerica.com. Even though both should arrive at the same location, if the bank security certificate is only configured for www.bankofamerica.com you will get an error if you leave the www out of your URL. The error message actually tells you how to fix the problem in cases like this one. Simply make sure you use the website address that supports the security certificate and you will not get the error message.

    Hi, Dave
    Whenever I try to go on a site that requires secure log-in, such as my bank, eBay, etc., I get a security warning pop-up saying there is a problem with the site’s security certificate. It says “the security certificate has expired or is not yet valid” and gives me options to continue yes/no or view certificate. I am operating Windows XP.

  • k

    Adjust your date and time. That fixes it. I kept getting it too and I fixed my date and time in windows and it went away.

  • Joshua Wyly

    Check your time settings. It’s probably nothing more than the year being wrong. :)

  • Shawn

    Hi Dave, I was wondering maybee you can help me here. You see I have the same problem, Everytime I try to open my email page which is hotmail, or any MSN.com page, and several other website pages that I know are good and safe sites I get the same message as everyone else here this page:

    There is a problem with this website’s security certificate.

    The security certificate presented by this website has expired or is not yet valid.

    This problem has been bothering me for ages now, almost a month and I still cant seem to find a fix, and yes my time is correct it is sychronized automatically online, and I even checked to make sure my clock in thbios is set properly which it is. I am really stumped, why do I still get the error message about the security certificates, and how can I fix it? My system clock is set correctly, and I have tried just about everything I can think of to fix this. Please help me if you can I would really like to be able to open web pages without going through ages of hassles just to check my email.

    Right now just to check my email I have to click “continue to website anyway” 2times before I can enter my password, then once again after my password which is 3 times to finally open a windows live account page, and then open my email in a different explorer window and click “continue to website anyway” one more time before I can finally get to my email. This is very frustrating considering once I am logged into my windows live messenger it should just open in one click and already have my password enetered when I logged into messenger. This is the case for other websites also. Juast that one is the most frustrating. I know that the websites should all have valid up to date certificates, but my computer does not agree. I have run many a virus scan using Kaspersky 6.024, and spyware scans using Ad-Aware 2007, I also clean up temp files regularly using the freeware program “Cleanup” (a great little prog).

    Any how I really hope you can offer me some idea about whats going wrong here. I am running Windows XP SP2 professional, I have had this problem for a while now and I just dont know what I can do to fix it. I have tried all I can think of to no avail. I am sorry for going on and on, I hope you understand my problem, Thanks

  • Shawn

    I really wish it was that simple, but unfortunately it is not. I have the problem with the server certificate errors, and it is very very frustrating because I can not find a fix for it anywhere. And the bigest thing I hear is that my time is wrong, well it is not. My system has got the exact right time in the bios and in the windows clock, down to the second it is exactly right hour, minute, second, AM / PM month, day, and year. They are absolutely correct.

    I am posting this at 9:01 PM eastern standard time in the year 2007.

    I have my clocks set correctly and I still have the server certificate error when opening web pages, particularly with MSN webpages, and Windows Live pages like hotmail and such.

    Any help at all will be greatly apreciated.

    Thanks

  • http://na MHussain

    I corrected date and time and this error of certification expiry disappeared.

  • http://na MHussain

    The following steps will help

    1. Check system time & date. Set it right.

    2. Go to Internet options > Content >Certificates > and delete any expired certificates.

    3. Go to Internet Options > Advanced tab > Under Security uncheck “Check for publisher’s certificate revocation”

    Also try to check or uncheck ” Check for Server Certificate revocation” if none of the above options work.

    If none of that works, I would scan the computer thoughorly for malware/viruses

    I had this same problem on 3 PCs accessing a site with https://

    … as well when I launched IE7 … it was slow … detecting proxy settings …. would show in the Status Bar.

    open Internet Explorer, now click Tools, click Internet Options, click the Connections Tab. Now click LAN Settings, you need to uncheck “Automatically detect settings”.

    That helped me … FYI !

    I just bought a desktop from Dell October 2009 without software warranty (because it cost $250 for one year). When I had the problem about “security certificate”, I called Dell to seek help, and guess what……they said it was a software issue and I have to pay $250 to have it fixed. My Computer barely passed it’s six-month and they wanted me to pay $250 just to have this “minor” issue fixed. Of course, I cannot afford it so I went to google this problem and wallah! It works. So now I learned my lesson and I want to share this to everyone …..DO NOT BUY DELL COMPUTERS!!!!!ALL THEY’LL WANT IS TO “BLEED” YOU OUT TO PAY FOR A PROBLEM THAT WILL ONLY BE FIXED BY JUST CHANGING THE DATE. Next time I’ll gonna buy a MAC, the price at the end is just gonna be the same without the virus….

  • Chip Doll

    Does / Is this effected by roaming profiles at all?

    I’ve a user that we have tested his link on two different pcs and both deny access, although another user can get to the same site with no problems.

    The baseline build is identical

    The IE settings are too

    (A roaming profile would not be effected by the date time thing, would it??) I think not but, you never know..

    Its a stumper…
