Alright, I have two people giving me different directions.
I have the server running with the server ip blank, like it should be. I have all the white-listed stuff ready to go and I can join it from this computer. I am using the ip4 address to join it and it works. When I put in the exact same address on the laptop, I get nothing.
What do I do now? I have seen videos and when they port forward, they set it to 25565, which is what mine is on. How could it be my ports? I have all the right things set in the server settings or else I wouldn't be able to connect to it at all.
