Could someone post a guide or at least tell me what I'm doing wrong?
I'm trying to make my own non private server.
I click start server.bat and it says failing to send heartbeat?
I haven't changed any of the files and the readme isn't helping. o.0
Maybe you're behind a router that blocks outgoing traffic to "non-normal" ports (where normal is 80 for HTTP and 21 for FTP or something)?
Typically, if at home, there should be no problems whatsoever. People may not be able to join your server if you don't configure port forwarding on your router, but you should still be able to send the heartbeat.
