<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="mso-fareast-language:DE">you can safely post the client.crt file - it is public info and useless without the key file.
<br>
<br>
Having said that, I just created a certificate set to expire on Mar 9 2037 and it passed the following command:<br>
c:\program files\openvpn\bin\openssl x509 -dates -subject -noout -in mycert.crt<br>
<br>
can you run the same command on the failing certificate?<br>
