Can't connect auth. server

Hey guys, running CSS server on linux box, after startup everything looks good, I can see the game running, but on connect I get this error

does anyone know what the deal is on this? I can't run it on 27015 because I have dod on that port.

Error is more than likely a steam issue, not your server, try using 27020 though.
