401 - Unauthorized is returned for a non-existing URL request

Issue

• HTTP/HTTPS requests for non-existing endpoints return 401 - Unauthorized instead of the expected response 404 - Not Found.

• Invoking a non-existing /test endpoint returns 401 - Unauthorized

  curl -v http://localhost:8181/test
  *   Trying 127.0.0.1...
  * TCP_NODELAY set
  * Connected to localhost (127.0.0.1) port 8181 (#0)
  > GET /test HTTP/1.1
  > Host: localhost:8181
