##### SUMMARY
<!-- Explain the problem/feature briefly -->
I encountered the same issue as #8303. I manually replaced `${VNCPORT}` with
8443 in `/etc/iptables/rules.v4`, and then re-executed
`/opt/cloud/bin/setup/postinit.sh`
After the modification, the VNC console page can be opened, but it is always
connected
I watched a lot of tutorials, but nothing worked

-->
<!-- Paste example playbooks or commands between quotes below -->

sed -i 's/${VNCPORT}/8443/g' /etc/iptables/rules.v4
sh /opt/cloud/bin/setup/postinit.sh
tail -f /var/log/cloud/cloud.out
~~~
<!-- You can also paste gist.github.com links for larger files -->
##### EXPECTED RESULTS

noVNC can be loaded normally
~~~
##### ACTUAL RESULTS
<!-- What actually happened? -->
