hey, chicago is unjoinable again, at least for me. Here is the output going into console when I try to connect if it helps:
Retrying connection to 74.91.113.242:27015, server requires lobby reservation but is unreserved.
Received game details information from 74.91.113.242:27015...
Adding direct connect IP to reservation 74.91.113.242:27015
[MM] Sending reservation request to 0.0.0.0:27015
[MM] Sending reservation request to 74.91.113.242:27015
[MM] Sending reservation request to 0.0.0.0:27015
[MM] Sending reservation request to 74.91.113.242:27015
......
This goes on and on until I have to force disconnect. Now when I try to attempt a connection again, I get the failed to join session error and following output to console:
Connecting to public(74.91.113.242:27015) ...
Server using 'public' lobbies, requiring pw no, lobby id 18600001af7e44f
RememberIPAddressForLobby: lobby 18600001af7e44f from address 74.91.113.242:27015
GameTypes: could not find matching game type "".
CSysSessionClient: Cannot join lobby, response 2!
So I guess the problem lies in the server not being able to respond to the reservation request?
Hopefully you find this useful
