Issue - Accelerated VM overview page returns permission denied error.
Environment - OnApp 4.2 and 4.3
Resolution - OnApp control panels running CentOS 6.x must have a valid SSL certificate installed as described at https://help.onapp.com/hc/en-us/articles/222051148-Setup-SSL-for-OnApp-UI-on-CentOS-6-0
Cause - The intermediate certificate must be installed using the update-ca-trust tool for our CDN systems to properly recognize the certificate. Otherwise certificate validation fails when the control panel connects to the CDN system and results in the permission error.
