Actually if you can't login with beta and ok with release look here

[class101 [deck]]

I had to place the switch -tcp to Steam.exe shortcut for being able to login with the beta client , no problems with release client

As of writing It seems the UDP servers are yet unstable

Without -tcp I'm stuck at login prompt that never disappear

Worked great for me. Thanks!

No problems

If you are not fine with modifying your shortcut do this instead

Hit Windows keyboard key + R and type

"C:\Program Files (x86)\Steam\Steam.exe" -tcp

(Edit your path to Steam accordingly, Windows sample)

Btw if you wonder where I have found this was because I had a VM with a steam release on it so I figure out was on Steam ends so I found this excellent kb article

I just found this little gem of a suggestion. Not only did it fix the failed logins, but, the client seems to be faster as well. Except for community pages that is.

When you right click a shortcut to Steam.exe, Properties, and you add -tcp at the end of the target command line, target should be showing as path\Steam.exe -tcp
