New Steam Client will not join game

A new steam client came out on March 5th that broke my game, the game gets stuck on joining…it will not load the map from the server. The server doesn’t give an error, I just get this from the client…the server has no log change with the new client.

Here is the log when it worked:

Here is the log now when it does not work:

Disregard the different ports.

I’ve tracked the problem down to the new steam client. I have a machine that has not updated the client yet and things still work…using the same dedicated server instance tested with that machine and a different machine with the updated steam client March 5 it hangs on:
[2019.03.07-15.43.35:456][104]LogNet: Game client on port 7777, rate 10000

Not sure where to look. I’ve submitted a steam ticket, it has been 3 days, no resolve yet. Thanks for any help.
