Cant detect servers when using openvpn

So I have an urbackup server that runs on a raspberry pi which is connected to my office using openvpn. In the office there is an openvpn server. I can ping back and forth but I cannot get the urbackup clients to discover the server. Any ideas on how I can make this happen? The openvpn uses 10.8.0.x subnet and my office subnet is 10.0.0.x.

It’s probably due to ports not forwarding properly via the VPN.

If you’re actually on different subnets than the server, automatic discovery won’t happen because you’re in a different broadcast domain. You have to be on the same subnet for discovery, you can still add the client manually.

ports are forwarded, I can access the server without any issues.

How do I add them manually?

in urbackup server web interface -> add new client
