Azure ML endpoint 404 error

Question

An Azure Data Factory pipeline for updating a trained ML model returns this error:

HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
Requested URL: /workspaces/xxxx/webservices/xxxx/endpoints/update

Diagnostic details: job ID xxxx. Endpoint https://services.azureml.net/workspaces/xxxx/webservices/xxxx/endpoints/update.

I don't even want to think about why it returned a HTML document... I am 100% sure that the endpoint exists and the key provided is correct. So what is my mistake?

Answer 1

Deleting and creating the endpoint again fixed it.
