Failed to connect to PurView caused CI tests failure

[windoze]

Recently we have CI test failure in every PR, the error message:

E           requests.exceptions.ConnectionError: HTTPSConnectionPool(host='some-purview-name.catalog.purview.azure.com', port=443): Max retries exceeded with url: /api/atlas/v2/types/typedefs (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f90c3e7ea60>: Failed to establish a new connection: [Errno 111] Connection refused'))

Looks like that we have some issue with the PurView service.

Please help to resolve as it affects all PRs.
