As the title says, different modes with public matchmaking (meaning regular & ranked) will lock up after certain periods of time. This does not seem to be a time based event. This issue seems to persist until server restart, with no lobbies open at the time.

Restarting the server seems to fix the issue, however not really feasible..

By "locking up" I mean returning NAT errors. Most common that has been reported in #bots-zone is 118-0521. This issue also appears to happen on the testfire, and was very prominent.

This issue happens due to the NEX server having "ghost lobbies", which we have not figured out the cause to. During high playtime hours, this issue is mitigated but during low playtime hours it appears. The client tries to NAT holepunch a non-existent host, and times out doing so because the host is no longer in game.
