I can find at least two posts that have been locked with no comments about this. I am also experiencing the same issue. I have a kiosk view that is passing through credentials. When I go directly to a dashboard view on browser load (ie: https://FQDN.domain.com/apps/platform/dashboard/24), it loads up with a generic ASP server error page the same as is visible in this question:
Modern Dashboard doesn't Load from URL
But if i go to just https://FQDN.domain.com first, it loads the default page fine. THEN if I put in the dashboard URL it works, same as this question:
Modern Dashboard Error on Load If Not Already Authenticated
Seems this has been an ongoing issue and is putting a damper on my attempt to create a nice NOC view. I'd like help with this.
