Ok, so everytime i start my server i try to join and it says Disconnected and on the run.bat is says my ipv4 address protocol error than my ipv4 address again, i have no idea how to fix it.
@TheNewPig Open the latest.log file with notepad, copy the content to http://pastebin.com, post the link here
@TheNewPig Restart the machine, might help for this one. Something else is already using the server port.
@TheNewPig Computer, might be the case that you have a server running already. So we restart the computer to start fresh again.
ok, done, ok now its saying when I start my server ''the server.jar is invalid or corrupted re download it and try again''.
