We are trying to create a new hosted feature layer, but are receiving the following error:
Unable to load https://<url>/rest/admin/services/Hosted/FeatureServer/addToDefinition status: 404
If I try to publish from ArcGIS Pro, as well, the feature layer is not published (though no error is shown).
What is intriguing is that URL https://<url>/rest/admin/ doesn't exist. Rather, we have https://<url>/arcgis/rest/
I am guessing there is a configuration problem somewhere.
Any ideas?
