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?
