After installation of OA Update 8, OACI VE console is not working for all virtual environments on a specific Virtuozzo host.

Web browser console log shows the following message:

can't establish connection to the server at wss://cp.domain.tld/213/5800

where 213 is the host_id of the Virtuozzo node and 5800 is the VNC port number the VE VNC server runs at.

There is no connection on port 80 from Branding host to this Virtuozzo node.


With Update 8, VE console was switched from Java applet to HTML5 based console utilizing HTTP web sockets with Branding host proxying connections to Virtuozzo node. To allow this, connectivity on port 80 should be provided.


Allow connectivity from Branding host to Virtuozzo node via backend IP address on port 80.
