Description of problem:
when using the current version supplied with RHV 4.4 SP1 VirtViewer v9.0-96 it is not possible to connect to VNC that is encrypted. My guess would be that the windows version does not actually use the CA supplied in that file via console.vv

The CA is supplied in that file like this:
[virt-viewer]
type=vnc
....

[ovirt]
ca=----BEGIN CERTIFICATE----\nMI...

Version-Release number of selected component (if applicable):
VirtViewer v9.0-96

How reproducible:
RHV 4.4 SP1 VM with VNC encryption enabled

Steps to Reproduce:
1. Make sure you have selected VNC and native client in RHV Manager
2. Click on Console
3. Download console.vv
4. use that file to start virt viewer

Actual results:
C:\Program Files\VirtViewer v9.0-96\bin>remote-viewer.exe -vvv --gtk-vnc-debug "c:\Users\username\Downloads\console.vv"
