Error starting OpenVPN Service

[Harmanogo]

Hi All,
I would appreciate some assistance. I am installing OpenVPN 2.5.9 on Oracle Linux 9.2. My server.conf is below. When I remove the plugin line for google auth, the service starts. That line seems to be the problem. The line reads: plugin /usr/lib64/security/pam_google_authenticator.so openvpn
I am not getting anything concrete when I run
# journalctl -xeu openvpn-server@server.service Not sure how to figure out why this is happening. Could anyone assist please?

I eventually found some info on this. Someone else reported on this. I changed the line to the line below and the service started.
plugin /usr/lib64/openvpn/plugins/openvpn-plugin-auth-pam.so openvpn
