"User already connected to the server" - SOLVED

[EP213]

Updated to v25 and now the server is only allowing one player in the server at a time, when the second player attempts to join they receive the following message - "User already connected to the server"

Ports are forwaded, no issues when we were playing the "onlinetest" version. Any help would be appreciated, thanks.

edit: solved lol, we both had no username set, so we set a username and i guess the server recognized us as different connections.
