Everytime I try to start the server it goes offline and I can't join I have done this numerous times but still no success. Any advice that could help this problem?

Hello! I want to ask the community on how to make a world for your server that you can do in singleplayer. There is a type of world that you can make to have no blocks only thin air. I would like to to this to have smaller man made islands instead of having to go higher up.
