Cause

This issue occurs if the subscribed catalog has an incorrect "Subscription URL" applied to it.

Resolution

To resolve this issue ensure the correct subscription url is applied on the subscribed catalog.

To do this:

1. Login to tenant organization where the published catalog is located.
   1. Then navigate to Content Hub -> Catalogs to see all catalogs.
   2. Beside the published catalog click the vertical ellipsis (⋮) and select 'Configure publishing'.
   3. Within the modal window that appears confirm what is the expected 'Subscription url' and take note of it.
2. Login to tenant organization where the subscribed catalog is located.
   1. Then navigate to Content Hub -> Catalogs to see all catalogs.
   2. Beside the subscribed catalog click the vertical ellipsis (⋮) and select 'Subscribe settings'.
   3. Within the modal window that appears enter the correct subscription url as identified in step 1c above.
   4. Click SAVE.

Catalog synchronization should automatically begin once the correct subscription url is applied. If it doesn't then manually click the 'sync' button.
