I configured SSRS in Native Mode and expected to be able to view report manager via my URL. But the image below was what I get, with no access to the "home" link where I could set up permission. What do I need to do to rectify this?
If I click on "Report Manager", renamed "Web Portal URL" in 2016 version, I get the error below
Service Unavailable
HTTP Error 503. The service is unavailable.
