This is for the game Starbound, but I cannot blame the game, this has happened every time. I will try to open a port on my router, in this case TCP port 21025, and then I will port it through using that as the start and end port, and then I will allow the port through my windows firewall. My friends cannot connect to my server, and sites like www.canyouseeme.org say they cannot find me on port 21025. What am I doing wrong!?
