Reproduction Steps

  • Removed ue4ss
  • Installed ue4ss manually same issue
  • reinstalled and updated and redone the whole server same problem

Update your instances by clicking on the down arrow on the instance tile on the main page, to refresh their config

I tried this but get the same error where it starts but then crashes ue4ss but i used another program and it works fine but i want to use AMP Instance Manager for the program - well this time it worked i tried this before and it didn’t work but it works now not sure what was going on but thank you for the help
