novnc console stopped working after configuring a domain certificate

Hi guys,
So a quick question, I had a working novnc console up until I updated the certificates to use our domain cert. From that point on nothing opens up.

I can see ssl errors in the messages log file on the host
ovirt-websocket-proxy: INFO msg:630 handler exception: [SSL: SSLV3_ALERT_CERTIFICATE_UNKNOWN] sslv3 alert certificate unknown (_ssl.c:897)

Has anyone encounter this?

BR,
Kostya
