Issue

“Couldn’t determine the URL to fetch an update from. You may need to install this server type manually.” I am not sure how to install the server type manually and need help.

Reproduction Steps

  • Created the server
  • Clicked Startup
  • Told me I have to install manually

Try stopping the instance, wait a couple minutes, then start it again and see if it grabs the update sources properly. Sometimes the forge manifest is hella slow
