So I am trying to run a OpenVPN server in a docker container on my VirtualBox Xubuntu VM and connect to the server from the hosting Windows 10. I ran the server, but I can't seem to connect. I disabled both firewalls (on the host machine/the client) and on the Xubuntu hosting the docker server (I ran sudo ufw disable and then sudo ufw status and it said "Status: inactive").
On Windows I'm using the OpenVPN GUI and this is its console output.
Here is my client .ovpn configuration file (I added the two lines:
cipher AES-256-CBC
data-ciphers AES-256-GCM:AES-128-GCM:AES-256-CBC
because before this I had another error "--cipher is not set. Previous OpenVPN version defaulted to BF-CBC as fallback when cipher negotiation failed in this case. If you need this fallback please add '--data-ciphers-fallback BF-CBC' to your configuration and/or add BF-CBC to --data-ciphers." and that seems to have fixed that issue):
