Error with server connection

[Valve]

I have weird error with connection to server.

Same world copied to computer and started with single player works fine, but mp doesnt.

I've been downloaded all files twice, removed player data from server, reset all inventory files and nothing have been solved this issue.

Also I tried remove region files from that area where I should spawn.

Other playes can join server with no errors.

Looks like I cannot figure this out myself.

Actually just solved this. Problem was Hardcore Ender Expansion's april fool.

Setting it off solved issue.
