Problems vertifyng server

Hello! I have a problem revertifying my server(s) and uploading a new one. I can see the server is online the my client (ip: 216.244.80.58:4000) but when I'm testing the connection when vertifying the server in planetmiencraft it says failed to connect the first time, when I then press test connection again it shows the loading picture and it just stays there no matter how long I wait. I kinda need to get these servers posted so it would be great if anyone could tell me why this is happening or if something is wrong. THanks!
