Recently, I've been attempting to get a server up and running again and well, I've port forwarded and have connected using my local IPv4 address, however the public IP address does not work, so I assume that the port is NOT open. I was wondering if anybody would have the will or time to assist me here or on discord or whatever and see what is the cause and so on, here's a few screenshots!
This is a way to tell if you've port forwarded correctly.
Visit: http://www.portchecktool.com/ and type in 25565 for the port.
If you port forwarded correctly, you should get something that looks like below.
not being able to connect to your external ip when you are inside the network is totally normal as you are not connecting externally, igf you are on the same network as the server you join with localhost (for same computer as server) or the local ip (different computer to server) and others who are outside of your network connect with external ip
