Some reason, yestoday i had a internet server up, and someone joined. I tried it today but apparently it doesnt work (Tested by two people). It may be the Add-ons, but im not sure. Ill try with Defaults like yestoday. If you want to check my server, ill try to leave one up.
Edit: Got server up, defaults add-ons, and i added Blockland into FireWall Exceptions. I also done my best to port Foward (Just incase).
Edit 2: Added Console.log for the server, while i got someone to try to connect.
Edit 3: Today i tried it, and it works.. Im starting to think that maybe some players Routers cant connect, while others can..
