Posted April 9, 201411 yr Hello! I've got a little problem and I don't know how to deal with it. So I've just recently started to fix the server version (works on singleplayer not multiplayer) and I started the server. It started normally but when I go to Mutliplayer on the client and try to join the server, I get: Failed to login: Invalid session (Try restarting your game) I thought I'd see an error in the console but I didn't, all I got was: [16:36:59] [server thread/INFO] [net.minecraft.server.network.NetHandlerLoginServer]: GameProfile{id='null', name='derpplayer'} (/127.0.0.1:1785) lost connection: Disconnected Anyone know what can cause this? Need anything like code or stuff just ask (not sure what to give you)

April 10, 201411 yr So I'm having a similar problem to this, except that when I click on the multiplayer option, the test server doesn't show up at all. Its essentially stuck at "Scanning for games on your local network...", and never budges. The server launches perfectly however. Not sure what I have done to not make the client acknowledge it though.
April 11, 201411 yr Edit: Thats okay..I managed to figure out what I did wrong without a sarcastic remark.
