Hello,
Testing the new 11.2, I was very excited by the new functionnality allowing to configure ArcGIS Server services directly from Portal for ArcGIS and not from ArcGIS Server manager:
https://enterprise.arcgis.com/en/portal/latest/use/manage-map-image-layers.htm
But whenever I access the settings of an item of a MapService, a pop up shows up:

The error is coming from the fact the ArcGIS Server web adaptor has the Admin access disabled so it should use the proxy I guess ?
Anyone facing the same issue ?
Thanks,
Best regards,
Nicolas
