It looks like you are trying to connect to legacy PIA servers with the port forwarding option enabled. This is no longer working on the PIA side so you will need to switch over to a next gen server. Assuming ca-vancouver.privateinternetaccess.com is the server you are wanting to connect to, simply go into your ovpn config file and change the URL to ca-vancouver.privacy.network. Start the container and monitor the logs--you should see a port get assigned and then, finally, a message saying [info] Deluge Web UI started. WebUI should be accessible now.
