The server references this property when the server performs origin header checks.

Default: If unset, the server uses the value that is returned by python's ` socket.getfqdn() `. You can view this default value by running the following command:

/usr/share/cb/virtualenv/bin/python -c 'import socket; print(socket.getfqdn());'

This property should be set to the hostname that users type in to access the server. See WebsocketOriginCheck, NginxWebApiHttpScheme, and NginxWebApiHttpPort.
