This is really strange
So far this only seems to affect Windows servers, but I see no reason why that should happen (except something related to firewall etc, but it's weird that it was apparently working before) ![]()
How often do you restart your server? Do you use the built-in "restart" command (or the built-in scheduler), or do you actually kill the process and start a new one?
Could you maybe share the latest server logs (for the Logs folder)? Maybe you could send them via PM to me?
//Edit: After some investigation, it seems like the UDP port sometimes still stays active for a brief moment after shutting down the server. If the server gets restarted immediately (either by the built-in restart command, or by killing the process and restarting it manually), this results in the old UDP listener not getting closed. This only seems to happen when binding to all addresses (i.e. if no specific server ip is provided). Apparently this was already happening in 0.3 (the previous multiplayer update). We're looking for a solution and will provide a fix for this ASAP!
