Steam updates breaks servers

The latest steam update breaks the servers:

I've tried to update 16 and 17 first
Both get stuck during startup.

I'll keep the others running without the update for now.

I have tweaked the servers steam.inf file.
Without updating the servers now show the latest version and I could connect with my latest steam client.

Server 16 and 17 are already updated and therefore broken at the moment.

But the other servers should now be usable till I find a proper solution.

Luckily I've stopped upgrading the servers after server 16 and 17.
Otherwise no server would be able to run anymore.

I hope I've fixed the problem.
All servers are updated now to v2.1.4.6.
