Hey!
Can you check the cockpit service from host
systemctl status cockpit
In case it is not started
systemctl start cockpit

This issue could be because of a firewall exception.
You can try this -
firewall-cmd --permanent --add-port=9090/tcp
firewall-cmd --permanent --add-port=9090/udp
systemctl restart firewalld

If the problem still persists, you should check for
systemctl status cups-browsed
In case it is not started, try starting the service
