Hi:

 

I use novnc console can connect to engine vm.

 

But when I using novnc console connect to other vm in other datacenter, failed.

 

The ovirt-websocket-proxy log is:

 

Jan 19 15:43:32 ooeng.tltd.com ovirt-websocket-proxy.py[1312]: 192.168.10.104 - - [19/Jan/2021 15:43:32] connecting to: ohost2.tltd.com:5900 (using SSL)

Jan 19 15:43:32 ooeng.tltd.com ovirt-websocket-proxy.py[1312]: ovirt-websocket-proxy[24096] INFO msg:824 handler exception: [SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:618)

 

What reason ?
