Players can't join. Error: "Invalid session (Try restarting your game)".
is your server time correct?
Well in PocketMine it's 20:54 and in Germany where I live it's 21:56.
the tokens are valid for several days, so check the date is correct as well.
But how? I don't know how to do this. Could you give me an instruction?
UPDATE: @dktapps The server.log is showing the correct date.
