Wondering if anyone could help with this issue that just popped up with our Portal. I have 2 web maps/web mapping applications that are set to be shared with "Everyone" . I copy the link over to a new browser so that I am not logged in to portal and the map begins to load, but after a few seconds the sign in screen appears and asks for a username and password.
We are at a loss as to what would be causing this as we have both "Allow access to the portal through HTTPS only" and "Allow anonymous access to your portal" checked.
