[TF2] Servers not reconnecting to steam after today's maintenance

[bottiger1]

After today's maintenance we have a few servers that never reconnected back to steam even after a map change. After 3 hours all our other servers have reconnected, even ones in the same physical server.

This hasn't happened for many years now. It might be prudent to investigate the steam reconnection code. It might have been broken due to the recent large update.
