Cisco Umbrella may act as a proxy for some of the domains used by your Morro storage system.  This can cause SSL certificate issues that prevent access to Morro's cloud services or to cloud storage backends.  You might see the following error message in the logs if Cisco Umbrella is causing an SSL certificate issue:

Account 'AccountName' gateway 'GatewayName' suspends requests to share 'MyShare' at January 1 2023 0:00 pm (UTC), because more file requests fail.

To avoid these issues, make sure that Cisco Umbrella is configured to allow direct access to the required outbound domains.

For more information about the required outbound domains, see:
