Error - FHIR Conformance SMART extensions not found at


Got the following error description:

We are receiving below error for logica sabndbox intermittently almost every night while running some automated smoke tests.

"FHIR Conformance SMART extensions not found at"

We have started seeing this error recently on this sandbox specially when app tries to pull conformance data. This is an intermittent error and seen more obviously while running automated tests in parallel. However we are not running any tests in parallel and have seen this error even manually while launching app.

We see this error while running our automated selenium smoke tests.
In those tests, we launch our app in the sandbox at least 12 to 16 times in an execution with no parallel execution. we see it more frequently, when we try to run these tests in parallel i.e. more than 2 tests running at the same time.

We have also seen this error while launching the app manually too.

After I had pushed the fix for , I got an email saying:

I work with Supresh. It appears the server is no longer allowing access to the conformance URL we have been using. To reproduce: curl "" {"error":"unauthorized","error_description":"Full authentication is required to access this resource"} (and HTTP/1.1 401 Unauthorized) While this other URL works, however using it would require us to change a lot of tests and configurations: curl -v ""

I informed them that they need to do the /metadata call.
