I created a server with the official minecraft server file. I've forwarded my port, and it functions just fine when I join. I can connect using the ip address, but when getting my friends to test it out they all get the same error no matter what I do.
Does anybody know how I can fix this? I tried consulting google about it but everything I've tried doesn't work.
Edit: I checked with someone who knew what they were doing and found the issue had to do with my IP address. For people experiencing the same issue, use you public IP address, not you private/internal one for a server.
