Question Rust server gets an error

[TrueAussie]

Couldn't create server on port 28015 (Startup Error) Couldn't Start Server

I get this message when trying to start my rust server
I've tried the following
-Checking task manager to see any background services
-Changed the max players to 30
-trying different ports such as 28016

Basically just keeps showing up, looking for any solutions
Thanks

Searching for what 28015 is used for, landed on this:
