[ovirt-users] oVirt 4 with custom SSL certificate and SPICE HTML5 browser client -> WebSocket error: Can't connect to websocket on URL: wss://ovirt.engine.fqdn:6100/

[Алексей Максимов]

Hello oVirt guru`s !

I have successfully replaced the oVirt 4 site SSL-certificate according to the instructions from "Replacing oVirt SSL Certificate" 
section in "oVirt Administration Guide"
http://www.ovirt.org/documentation/admin-guide/administration-guide/

3 files have been replaced:

/etc/pki/ovirt-engine/certs/apache.cer
/etc/pki/ovirt-engine/keys/apache.key.nopass
/etc/pki/ovirt-engine/apache-ca.pem

Now the oVirt site using my certificate and everything works fine, but when I try to use SPICE HTML5 browser client in Firefox or Chrome 
I see a gray screen and message under the button "Toggle messages output":
 
WebSocket error: Can't connect to websocket on URL: wss://ovirt.engine.fqdn:6100/eyJ...0=[object Event]


Before replacing certificates SPICE HTML5 browser client works.
Native SPICE client works fine.

Tell me what to do with SPICE HTML5 browser client?
