Issue

I made a new instance of a Minecraft Forge server. The server started fine, but in the field where I usually find the primary endpoint, there is nothing.

Reproduction Steps

  • create new instance of minecraft forge 1.20.1
  • configure server (just primary configuration for sleep mode, minecraft etc.)
  • Start instance
