Server Disconnect on Experimental Branch

I have been waiting to play rust experimental but when I try to join the dev server it just disconnects me. Can U plz fix that

The experimental server isn’t always up, for one thing.

For another, do you have any security software installed?

Microsoft security essentials. I see the server list. Its when I connect it just says server disconnect

press f1 after a failed attempt, it probably shows the reason there.
