Currently, there is an issue in which the Test instance of the ARS will immediately reject attempts to POST results back with a 403. I am currently working with ITRB to resolve this, and it looks very likely to be a configuration or environment issue rather than a bug in code.
ARS CI is running the same code and does not do this
CORS is enabled and the method being hit is csrf_exempt
The ARS logs acts as though the results were never sent, but asynquery_status endpoints for the relevant ARAs shows that they created and sent the results
The ARS Test server will accept POSTs of results that are sent from the same AWS instance that it is running on
I am currently working with ITRB to get the information needed to diagnose, but I suspect something with CORS/CSRF or possibly SSL
