I am trying to change my OpenVPN server from my Windows tower to my Linux (CentOS 7 Min) with out having to re-issue all the certs. For testing reasons, i created new certs in the linux environment and connected to the server from my Windows tower to make sure the firewall was configured correctly. Everything worked but when I transferred over all the existing certs from the Windows tower, I am getting a
"VERIFY ERROR: depth=0, error=certificate signature failure:..."
Initially my linux openssl was out of date and i didn't realize until after i transferred the windows files, so i had to update that.
Now both versions of OpenSSL are up to date (Windows: 1.0.2k 26 Jan 2017, Linux 1.0.2l 25 May 2017) and verified my Client cert with the ca.crt through
openssl verify -CAfile ca.crt Client.crt
and it comes back good.
Any help would be great, re-issuing the certs just isn't a good option at the moment.
