The Commvault DR backup to cloud (an option within Control Panel of Commvault console) was reporting failures.
The CVCloudService.log reported a ''CURL perform failed" error and suggested SSL certificate problem.
As it turned out, the Commserve was not able to reach https://cvdrservices.metallic.io and was being blacklisted by the firewall. One the web portal was added to the whitelist, the Cloud DR backup to cloud completed ok.
