Solved Can't connect to my server (non-Steam, unsupported)

Hello.

I made a server but when i try to connect to my server its stucking at Steam auth for 4-5 seconds and its brings me to the main menu and says "Could not connect to the server (14) Please try again" I can not join from localhost.

This may be more descriptive:
I'm Connecting: http://i.hizliresim.com/AJM9P0.png
Steam auth thing: http://i.hizliresim.com/v42OGz.png
And the error: http://i.hizliresim.com/L3zBzo.png

What can i do?
Btw sorry for my English. I'm from Turkey.
P.S. I'm not using steam version. And i have 8 plugins. I have to tried to delete plugins but its stucking on steam auth.
Console error:
