I am having the same problem and the response I got from GS was it appears to be an issue between the servers and STEAM. Just got home and my server was down all day. Restart it and it works fine until the next crash and then it does not reconnect with STEAM. I tried the ticket route and still no fix....Hi,
I apologize for the difficulty you are having. Unfortunately, this does appear to be a common issue. The only thing we can suggest at this time is to issue a server restart to bring the server online. There are some who suggest the issue may be related to a steam server communication issue and others who state their servers are terminating but not restarting after the crash.
If you were interested, you could read more about this specific issue on the official splash damage forums:
