The web application embeds an iframe element with the src attribute set to the url of the report. The report is rendered bu I interpret this as meaning the report has tried to fire some notification messages (loaded, perhaps) and failed with this message.

 

Any ideas or help would be appreciated as I have exhausted the internet searching for a solution!

Have you included the rs:embed=true query string parameter in the report url? If you have not included the rs:embed parameter PBIRS will try to render all the navigation elements around the report which might be what is causing this issue.
