Logged into ArcGIS Enterprise v11.5 as an administrator, we cannot change the ownership of any item of type "Data Store". The portal simply reports "Error Unable to change owner" with nothing in the Portal logs. The Server logs contain this for approximately the same time . . .
Webhook log: Error in Webhook Processor. init WebhookProcessors failed. Initialize Webhooks Database failed.Create Webhooks Database failed. Could not connect to the ArcGIS component at URL 'https://MY.DATASTORE.SERVER:2443/arcgis/datastoreadmin/createWebhooksDatabase'. The ArcGIS component on that machine may not be running or the machine may not be reachable at this time.Error: Connect to MY.DATASTORE.SERVER:2443 timed out.
. . . but I'm pretty sure that's unrelated since I'm not talking about ArcGIS DataStore, but rather about items representing data stores registered with ArcGIS Server; plus I tried re-homing multiple items on multiple occasions, and this error only shows up in the logs once.
Some other observations:
- The data stores in question *do* validate for their server
- The items in question are *not* shared with *any* groups, so that rules out the easy shared-update-group diagnosis.
- We recently upgraded this instance from v10.9, and we're having no such troubles in other environments still running v10.9. Is this a bug introduced at 11.5, or something caused by upgrading from 10.9?
- I've tried making new data store items, and I've had the same trouble with them as with ones that have been around since before our 10.9-to-11.5 upgrade.
