I am connecting to a website (via Firefox 6.0.2 on Mac OS X 10.6.8) I know is legitimate, and the connection worked up till yesterday. However, when I connected to day I got the following error:
An error occurred during a connection to [domain].
You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information:
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)
Is there a way to fix this?
