ANSWERED Trying to setup RPi5 torrentbox but can't get connection at all on VPN tunnel interface, or no peer connections on any interface

Not sure if this is a VPN or qbittorrent issue but here goes...
 

I've been running qbit on my PC and pushing the files to a Samba share on a raspberry pi which was working ok but I didn't want to have my PC on all the time so I've bought an RPi5.

On PC I've been using AirVPN with Eddie UI but Eddie doesn't work on RPi5 yet, so I've tried both AirVPN suite and after that failed, wireguard using the configs provided by AirVPN.
Both instances of this connect me to my AirVPN tunnel, I can see the connection in my account and the public IPs are from another country, so VPN seems to be working in both instances.

Now when I come to install and use qbittorrent, it's installed and the web interface is fine, but I can't get any connections. If I specify my VPN tunnel as the network interface to use, I get the red globe icon so no connection to the network (I think?) so if I change to all interfaces, I get the flame icon so connection but torrents are stuck at retrieving metadata and I get no peers.

I have the correct port configuration, the port from AirVPN is forwarded to my RPi and configured as the port in qbit.

I've specifically selected the eth0 interface (which I verified is still using my standard public IP address) and it got past the metadata stage and connected to come peers. I quickly switched it back to the tunnel interface so I'm not downloading off-VPN and I lost the connection status again, but retained the connection to those peers and am still downloading the files.
So the issue is with the tunnel interface obtaining the initial connections, is that a port issue? I've tried several port options.
 

Not sure what else needs configuring?

Managed to solve this from the looks of it. The IP address needed to be bound to the IP of the tunnel interface too
