I change the hostname of my hosted engine using script below:

However, as shown attached, the old hostname of "ovirt-engine.pbtech" seems to still be expected for some reason.  As a result I cannot connect to VMs via console.

Any idea on how to make WSS to use the proper hostname?

In file "https://www.ovirt.org/documentation/how-to/networking/changing-engine-hostname/" I defined "PROXY_HOST=FQDN" then restarted ovirt-websocket-proxy.service but no change.
