Strange lua error

Hi all. When I go to a friend’s local server, the following error appears. My friend drives normally and I see his ping. But I’m standing still at his place (despite the fact that I’m driving at my place) and instead of a pingle, she sees a question mark.

This LUA error can be ignored, since the server is local your friend needs to connect to the local IP, not the server IP. I think it’s like 127.1.1 or. . .something. . . @Protogen_1 what’s the thing you’re supposed to join if the server is on the same local network as the PC?

127.0.0.1 is localhost (host only)
What the user is describing reffers to UDP traffic being blocked
