I have setup the free minehut server and I've never got it to work. On the website it says online. Using Windows 10 64-bit, using Xbox App and Minecraft Launcher. I go to Servers > Add External Server name, server address and port 19132. Says locating server I try to join it and error message "unable to connect to world". Please help! I'm so stuck how to join the server.
