Problem Description

Issue

I’m trying to create a server with over 70 mods that all work on 47.4.10 but the list of servers does not have that option for Minecraft Java 1.20.10 although it is the recommended version of Forge for that Minecraft Java version.
It is failing to start although I’ve changed the server configurations and added the proper Forge installer.
Need help to solve this ASAP.

Reproduction Steps

  • reinstalled the server
  • uploaded the proper version
  • added the version to the list of available versions
  • modified the server configuration
  • added all the mods
  • tried to start the server

It’s in the list. Click on the dropdown and simply start typing the version you want.
