Unable to load feature service after I upgraded to Enterrpise 12.0 from 11.5

Question

Hi All,

I've recently upgraded Enterprise11.5 to Enterprise12.0. Everything seems working Portal, Server, Datastore, Image server.

All registered Map services are working and rendering except Hosted Feature services. When I restart the server machine, these hosted services would load for a short time and the same error continues

Any help is much appreicated

You seem to be having a CORS related error based on the error message. Has your Portal URL been added to the "Allow origins" on the Portal site that is hosting your ArcGIS Data Store?
