Troubleshoot the “Secure Connection Failed” error message

If Firefox can’t access a secure site (one that starts with https:) you will see an error page with the heading, Secure Connection Failed, and a message about the error. This article will describe some of these error messages.

Certificate warnings

Self-signed certificates make your data safe from eavesdroppers, but say nothing about who the recipient of the data is. This is common for intranet websites that aren’t available publicly.

Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number. (Error code: sec_error_reused_issuer_and_serial)

This error alerts you to the fact that the certificate the page you’re visiting uses has a serial number identical to one you’ve already accepted. This warning cannot be bypassed using the method below.

 

Bypassing the warningYou can tell Firefox to bypass these certificate warnings. You should only bypass the warning if you’re sure that the site is legitimate. Legitimate public sites will not ask you to do this. An invalid certificate can be an indication of a web page that will defraud you or steal your identity.

  2. Click Add Exception…. The Add Security Exception dialog will appear.
  3. Click Get Certificate.
  4. Read the text describing the problems with this site.
