The server didn't respond. How can I fix this?/ I am running this gamemode on my home server. Any ideas??

a) The server is off.
b) You're connecting to the wrong IP or on the wrong port.
c) Your client version doesn't match the server version.

That are about all the possible causes. Usually it's the latter.

Thank you. The server version was 0.3e
