mostly the 'master server error' happen when server is started and 1st player will join

if server is online it can crash at random moments

[2017/05/13 23:23:06] ...master server error: (1) no requests

[2017/05/13 23:28:18] ...master server error: (18) You are not connected.

when this happen the server is still running but cannot be found with the maniaplanet client
