I don’t host a server over Radmin myself though. My friend is, and trying to connect to him using a his Radmin VPN IP and trying to connect with Proton VPN on just doesn’t works.
I better wait for ISP to just respond sometime later regarding the issue, because i really hate using Proton VPN to play BeamMP, let alone try to connect to my friend’s server.
I won’t even try any of that because at the end of it it’ll still not work, it’s an ISP issue.
