Saving a blank Map Viewer Classic map in AGO prompts for user/pass to our on premises Portal?

[MichaelSnook]

Hi...this is a weird one that seems to have just started.  When saving a map in Map Viewer Classis in our Organizational AGO account (even a blank map) we are prompted for a login to our external on-premises portal.  I can't find anything that would be referencing back to our portal that is not shared publicly.  Any ideas would be great!

Thanks.

Is there something in the basemap or the map's locator that isn't shared publicly?

What's the URL of the map?

That's the weird thing...the 2 utility services (printing, and Directions/Routing) that we have set in AGO use our Portal but they are both shared publicly.  The default basemap is just ESRI topo and the geocoder is the ArcGIS World Geocoder.  Also our basemap gallery group is shared publicly as is everything in it.

Here's the test map url:

Hmmm. I don't see a login prompt over here.

It only happens when saving the map.

Well, I only have access to "Save As", but it works fine. I was able to save a copy to my own org:

Yeah...it only happens when saving a new map...time for a ticket!
