NoVNC console implementation in CloudStack

I'm having an error with ACS 4.15.1 and VMware 7 console proxy. Error I'm getting on Console Proxy VM is "Error on connection to websocket: No subject alternative names matching IP address <ESXi IP Address> found." How can I modify NoVNC or Websockify to use FQDN instead of IP address?
