Portal Map Viewer and Extent Options Fail

[ODWC_GIS]

G'day, All!

Federated Enterprise 11.1, no 'reverse proxies'

Even while using Incognito Mode (cleared cache):  Trying to Interact with Portal Items generally fails...

"Open in Map Viewer" results in a blank white screen.  "Page Unresponsive"

"Open in Map Viewer Classic" usually results in a map containing the Item of Interest.

Settings > Edit Extent  ...Results in a "Failed to Fetch" error.

Edit Extent in Portal

Has anyone else here encountered similar?  Did you find a solution?

Have you checked your datastore?

In what way?  I know it's there...  I use ArcGIS Pro to publish things from it to the Portal&Server all the time.

Sorry, I should have been more specific. Have you run a describe datastore?  Whenever I run into issues where items are not displaying it usually comes down to the datastore being messed up.  That message "Failed to fetch" can indicate the datastore is not happy. 

I would run a describe datastore, I would also look at your Portal index and see how it looks.
