Problem Description

Issue

I can’t install Forge as a base for the Server. Every time I tell it to install Forge in the Server Settings, it gives me an error talking about a “Missing URL” and says I have to install it Manually.

Reproduction Steps

  • I installed a Basic Java 1.20.1 server to start the Instance, and then went to the Server Settings to try and switch it over to Forge.
  • I clicked the Drop Down menu and selected ‘Forge’ on the options, and then clicked the Install/Update Button.
  • Instead of doing anything, it gives me an error pop-up telling me that the server “Can’t find the URL” and that I should “Try Installing the files Manually.”

Did you try again after waiting a bit?
