you can safely post the client.crt file - it is public info and useless without the key file.
Having said that, I just created a certificate set to expire on Mar 9 2037 and it passed the following command:
c:\program files\openvpn\bin\openssl x509 -dates -subject -noout -in mycert.crt
can you run the same command on the failing certificate?
