If you go on my Minecraft server, and play… At some point then out of the Minecraft server goes out, and would like to go back in… Can't? Can someone help me? (again more understandable: I join, then I leave, want to join again but then it does not work.) Then there's either "Internal Exception: java.io.IOException: An existing connection was closed by the remote host" Or there's only "Disconnected". I urgently need help.
Is it possible, if you connectest again after the error?
With me yes.
The server (if you rented it) has to be booted first, because after a certain amount of time, when you go offline, it will switch itself off. Normally it should go after one or two try again.
No
It's not working.
Is it, if you restart the server. If not, re-install the server. That should fix your problems
