Zen server in Unreal container has insufficient storage

Hi, I had the same issue on a standard (non docker) machine,
changing the zen storage location solved it for me:

  • Open BaseEngine.ini (found in UnrealEngineVersion\Engine\Config\).
  • Locate the [Zen.AutoLaunch] section.
  • Change the line: DataPath=%ENGINEVERSIONAGNOSTICINSTALLEDUSERDIR%Zen/Data
  • to: DataPath=%GAMEDIR%LocalDerivedDataCache

This will ensure that the cache is stored within your project folder instead of the default location.
