Secure Connection Failed

I usually use Mozilla Firefox 99% of the time in browsing websites. Google Chrome and Safari are just my alternate browsers. Recently, when I was trying to access my online bank account, I am confronted with an error page saying "Secure Connection Failed".

At first I thought the banking site was temporarily down as I got an email notification few days ago about some scheduled downtime. So I checked that said email only to find out that the scheduled downtime was already 3 days ago. The site must be up already!

I tried a lot of troubleshooting procedures in Firefox including clearing the cache and resetting but the issue remained. I tried to access the same site with Google Chrome and the same issue persisted. I almost gave up and wanted to call the bank to verify if the problem is from their end. Then I re-checked the error code that says "sec_error_revoked_certificate" so definitely, it is a website certificate issue.

So instead of calling the bank, I checked my Firefox browser settings and the steps below resolved the problem.

Fixing sec_error_revoked_certificate error in Firefox

The problem is caused by a default setting in Firefox. Do the following steps to fix the problem:

  1. Open Firefox
  2. Click on the Settings button, then click on Options.
    Firefox => Settings => Options
  3. When using the menu bar, you can click on Tools menu and then click on Options.
    Firefox Tools => Options
  4. In the Options dialog box, click on the Advanced tab.
  5. In the sub-tabs, click on Certificates.
  6. Uncheck the option that says "Query OCSP responder servers to confirm the current validity of certificates".
  7. Click OK.
    Uncheck the OCSP option
  8. Now, the problem website will now load normally.

NOTE: The certificate issue will not have a problem if you are 100% sure that the website that you are using is a legitimate website and that your computer is protected by an up-to-date antivirus software.
