Can't connect to standalone OpenVPN with docker-compose

[githilman]

Try to run this with docker-compose with my existing OpenVPN server but still the UI can't connect to the existing OpenVPN.

Here's my docker-compose.yml

openvpn-ui:
       container_name: openvpn-ui
       image: d3vilh/openvpn-ui:latest
       environment:
           - OPENVPN_ADMIN_USERNAME=admin
           - OPENVPN_ADMIN_PASSWORD=admin
       privileged: true
       ports:
           - "8080:8080/tcp"
       volumes:
           - /etc/openvpn:/etc/openvpn
           - ./db:/opt/openvpn-ui/db
           - /etc/openvpn/server/easy-rsa:/usr/share/easy-rsa
           - /etc/openvpn/server/easy-rsa/pki:/usr/share/easy-rsa/pki
           - /var/run/docker.sock:/var/run/docker.sock:ro
       restart: always

Here's the logs:

Hi,

You should change the Management Interface Adress in OpenVPN UI Settings.
Set it to the IP of your docker host, eg. : 10.0.0.1:2080

('openvpn' will never resolve to the right IP to connect to)
