Cause

This issue is typically caused by the expiration of the admin credentials utilized for Location Manager connectivity.

Resolution

1. Verify the administrative account utilized for Location Manager authentication to ensure the password has not expired.
2. Refer the "resetting-expired-passwords" documentation to update the local user credential if an expiration has occurred.
3. Access the Global Manager UI and navigate to System > Location Manager.
4. Locate the target location under the Locations section and select Actions > Edit settings.
5. Update the administrative password in the Location Manager section for all applicable locations.
