Looks like a network failure with your server, not something we can fix.

Do you know how to fix ?

sudo ufw allow 28015 if I enter this into a dedicated server will it help me?

I'm not really familiar with Linux networking anymore, sorry.

I'm assuming you're on a Debian-based distro.

First, disable ufw to test if this is what's causing your issue:

$ sudo ufw disable

If this doesn't resolve your problem then you have other networking issues. If it does, then (assuming the default ports for rustserver):

$ sudo ufw allow 28015/udp
$ sudo ufw allow 28016/tcp
$ sudo ufw default deny incoming
$ sudo ufw default allow outgoing
$ sudo ufw enable

NOTE: if your server is on a router and your port forwarding is using different numbers for internal/external then it's the INTERNAL ports you need to set. If you're using a commercial hosting service then you can ignore this.

You can check it like this:

$ sudo ufw status
