Who can tell me why the ip address turned red?
That usually means your ip has blocked ports for the game
I didn’t touch anything. How to fix it?
well first is this a rented server or on you home computer?
if it’s rented you will have to check with your provider on how to open the ports
if its your home computer try shieldsup to see if they are blocked here is the link
if they are not blocked it will show closed or open
start from there
