Unable to enable Location Sharing

Error Message

When attempting to enable location sharing in Portal for ArcGIS, the following error message is returned:

Error:   
Unable to enable Location Sharing

Note:
Location sharing is known as 'location tracking' for Portal for ArcGIS versions 10.7.x to 10.9.x. 

Cause

• A previously created Location Sharing service is detached and the ArcGIS Server is still referencing the folders from the service, which prevents enabling Location Sharing. Refer to Portal for ArcGIS: Manage location sharing for more information.
• Ports 9220 (HTTP) and 9320 (TCP) are closed. Ports 9220 (HTTP) and 9320 (TCP) need to be open for the ArcGIS Server site and the federated ArcGIS Server sites to communicate with the spatiotemporal big data store.

Solution or Workaround

Remove the detached item and folder

1. Navigate to the ArcGIS Portal Directory. The URL is as follows.

https://<machine_name>.<domain>.com/portal/sharing/rest

3. Navigate to the bottom of the User page.
4. Under Related Resources, click User Content.
5. On the User Content page, under Folders, click the Location sharing folder.
6. On the User Content - Folder page, under Items, click the item to be deleted.
