Azure Form Recognizer Generic error during prediction

I've been using azure form recognizer for a few months now, and I'm overall quite happy with it, but today we've run into a problem which doesn't really hint as to what the problem is:

"analyzeResult": {
                    "errors": [
                        {
                            "code": "3014",
                            "message": "Generic error during prediction."
                        }
                    ],
                    "version": "2.0.0"
                },
                "createdDateTime": "2020-07-27T16:35:17Z",
                "lastUpdatedDateTime": "2020-07-27T16:36:20Z",
                "status": "failed"

It seems to happen with TIFF, PNG but I have not tested it with PDF. The image quality is very high in all cases, and it really can't be explained easily.

Has anyone run into this before, and was there a solution to it?
