Published a service to ArcGIS Server (v10.61) with no errors. I can navigate to the REST endpoint from ArcGIS Server Manager By clicking the link under Capabilities (where I'd expect to see the service details), but I get a blank screen.
In Portal, I can see the service and when I open the Service Overview and click on one of the Layers in the service, it takes me right to the service URL and it looks how I'd expect.
when I navigate to the REST endpoint from Portal, I stay logged in to Portal and I THINK that's why I can see the service details that way.
So my question: why can't I see the REST endpoint when I navigate there from ArcGIS Server Manager when I'm logged in to Manager with the SAME USER as on Portal?
