Install a Fabric Snapshot 1.16.3-rc1 server through the Control Panel (Servers → Select your server → Game servers → Add Game Server → Fabric Snapshot 1.16.3-rc1)
Server was quick to setup and the introductory discount made it cheap to test out if I like the hosting UI or not. They have a wide variety of modified game servers(minecraft modpacks, etc.) which are easy to setup and debug; In one case where I was getting an error I got a quick response which solved the issue right away.
