I launched the ML backend, but it appears as Disconnected after adding it in the Label Studio UI

Your ML backend server might not have started properly.

1. Check whether the ML backend server is running. Run the following health check:

   curl -X GET http://localhost:9090/health

2. If the health check doesn’t respond, or you see errors, check the server logs.
3. If you used Docker Compose to start the ML backend, check for requirements missing from the requirements.txt file used to set up the environment inside Docker.
