I found this in some the agent logs this morning on the client (C:\Program Files (x86)\CloudVolumes\Agent\Logs):
"WinHttpSendRequestWithSSLCertValidation: WinHttpSendRequest failed (error 12175)."
When I log into my App Manager portal I get this popup. I am not sure if this has anything to do or an indication of the configuration problem.
I found the following KB article VMware Knowledge Base . I changed the the HKLM\System\CurrentControlSet\Services\svservices\Parameters\EnforceSSICertificateValidation from 1 to 0 on my client pc then rebooted and the issue looks to have gone away and I am connecting now.
Wish the SSL certificate stuff a little easier to manager and configure from the portal GUI. I am not really calling this a resolution, but a good enough work around for the evaluation for the product at this point.
Hope this helps someone else.
