Hi @ohmex, Thanks for reporting! It is for some reason can't find your server.conf file. Could you share your docker-compose.yml configuration file please?

Thanks.

OK, I see the problem:

volumes:

• ./pki:/etc/openvpn/pki
• ./clients:/etc/openvpn/clients
• ./config:/etc/openvpn/config
• ./staticclients:/etc/openvpn/staticclients
• ./log:/var/log/openvpn
• ./fw-rules.sh:/opt/app/fw-rules.sh cap_add:

You need to update volumes with server.conf and recreate container.

       volumes:
           - ./pki:/etc/openvpn/pki
           - ./clients:/etc/openvpn/clients
           - ./config:/etc/openvpn/config
           - ./staticclients:/etc/openvpn/staticclients
           - ./log:/var/log/openvpn
           - ./fw-rules.sh:/opt/app/fw-rules.sh
           - ./checkpsw.sh:/opt/app/checkpsw.sh
           - ./server.conf:/etc/openvpn/server.conf
