Friend's can't find my server. Says server could not be found

When I give my friends the IP to connect to my server it says server could not be found. When I go to http://canyouseeme.org/ it says it can see my service and my ISP is not blocking port 30120 but yet when I give friends the IPv4 address to connect to the server it still says server could not be found. Any suggestions?

Have you set up your server key?

Is the 30120 port open for both TDP and UDP?
Is it the right IP you’re giving them?
Could also put a easy name for the server like, “potato” and let them search for the name?

It might be silly to double check everything but trust me it always pays off. :slight_smile:
