Problem Description

Issue

I wanted to install some mods. I had to click the Update button very very very often because it is always only a few things installed. Server error 431 when I want to install the rest of the mods.

Reproduction Steps

  • Configured the main options for the server
  • Downloaded the mods into the File Manager
  • Updated my Server in Status multiple times to install the mods
  • Server error 431 after I nearly installed everything

Take a look through this guide here and double-check that you’ve installed the mods correctly:
