Server looses connection

[cheerp]

current-updated linux server apparently looses connection to the central servers after some time/days.
Effect is, the server vanishes from the server lists, and therefore players cannot connect.
After a restart, the server is back (for a time). This happened at least two times now, on two LV servers each
