You can connect to your server using two methods: 1. either joining directly; or 2. joining via the lobby. Firstly, in order to connect directly, you will need to find your server's IP Address, this is usually the server name followed by .minehut.gg. Once you have that, you can connect to it from the Minecraft multiplayer tab. Secondly, you can connect via the lobby, by joining mc.minehut.com and then executing /join followed by your server's name.
