Answer 1

I am using SSRS 2017 and was running into this issue when trying to load a report into my MVC project using URL Access. The issue for me had to do with session.

To check this for yourself, you can try deleting the RSExecutionSession cookie and reload your report. Unfortunately, this is only a temporarily fix.

If this does work, try adding rs:ClearSession=true to your query string.
