Hi Adam - can you check and sync time on your KVM hosts, management servers and
CPVM using ntp? This is because SSL-enabled connection are time sensitive.
In order to test VNC directly, you can ssh into the host and do something like:
# virsh list # find the VM
Then run dumpxml and grab the IP/port and password, for example:
# virsh dumpxml --security-info s-180-VM | grep vnc
<graphics type='vnc' port='5901' autoport='yes' listen='192.168.1.10'
passwd='_u6LayCdnCrr_JuUwCrq2A'>
If you're on the management network, you can use any VNC client and details you
find to connect to the VNC directly. I often connect virt-manager (UI) to a KVM
host over SSH and use the console directly (the only trick is to grab the
password, by clicking the information tab -> go to VNC -> click on show
password -> copy and use it to see console).
Regards.

I agree, try checking the number of concurrent connections as well as
increasing the CPVM capacity.
Also check the network for any glitches / lag between the CPVM and the KVM hosts

Do you know how many concurrent access to VNC from your user ?
Or you want to increase the Console Proxy Capacity?
Also, please make sure the console proxy Ip/Network is up when you having
issue on it.
