Apache quits. Certificate expired? No!
I have apache 2.2.3. It's been running for a couple of years on Scientific Linux, currently 5.5. Yesterday it stopped running. The error message says
Certificate not verified: 'Server-Cert'
SSL Library Error: -8181 Certificate has expired
Unable to verify certificate 'Server-Cert'. Add "NSSEnforceValidCerts off" to nss.conf so the server can start until the problem can be resolved.
I followed that suggestion, and it started up OK. Now I want to figure out why it happened.
The obvious thing to check is the expiration date of the server certificate. It's a proper one purchased from comodo.com, and it has more than a year of life. I don't know where else to look.
When I started to dig into things I got very confused. Both mod_nss and mod_ssl are installed. They do almost the same thing. Could that cause problems? Why would it go bad suddenly when I haven't changed anything recently?:confused:
