I bought the game yesterday and I’m trying to play with my friends.
They are online right now on a server, I can see the server online too, but when I try to connect, I get the error message “ConnectionFailed”

I’ve tried to change my ip, restart steam several times, checked firewall, put in an exception for port 28015 on my router, and nothing solves the problem

I can ping the IP address, and other servers work fine

any idea?

try right click on Rust in steam - local files - verify integrity
Thats helps me.

Ty, ryziak
but I tried that and it didnt help either
I even tried to re-download all the content to another HD

Post a photo of your console please?
