Unable to connect:: Host_Error: Unexepected authentication protocol

[cryptodan]

Server OS: Ubuntu 10.4 LTS 32Bit Fully Updated
Processor: Dell PowerEdge 2600 Dual 2.8Ghz Xeons
Ram: 3Gigs
Game(s): AG2
Start Up Command: ./srcds_run -game ag2 -port 27017 +ip 192.168.1.2 +maxplayers 16 +map pg_crossfire_final -autoupdate -steambin /home/srcds/steam

Server starts up fine and I can see it on the Steam Master Server list as Cryptodan's AG2 Server

However, when I connect I get this: Host_Error: Unexepected authentication protocol

The server is fully updated, and I have all the needed ports open.

Also I get this in my console:

Code:
