Can't connect to my mc server

Hi, i did a fabric 1.21.1 server to play with friends, and it works pretty well with localhost, but with the shared ip, provided by the agent, i can’t connect to the server. Is it normal ? It just say me “failed to connect to server, disconnected”

Well the tunnel doesn’t seem to work

Hey,
maybe it could help to restart your system or changing the tunnel / agent
