Install a NeoForge 20.2.92 (MC 1.20.2 ) server through the Control Panel (Servers → Select your server → Game servers → Add Game Server → NeoForge 20.2.92 (MC 1.20.2 ))
Every server I have had with Scalacube has been great, runs well and sets up so quickly. I have used servers for Palworld and Minecraft and no issues even in Palworlds initial start when other companies struggled to keep up. Would reccomend.
