Haha, option B with iptables? That's like using a sledgehammer to crack a nut. Firewalld is the modern way to manage firewalls on Linux.

Option D is definitely the way to go. Reloading the firewall after adding the service is crucial to make the changes effective immediately.

Thanks for the reminder, I'll make sure to use firewall-cmd --add-service=https --permanent --reload next time.

Don't forget to include the --permanent flag to ensure the rule persists across reboots.

I agree, using firewall-cmd with the --add-service option is the correct way to allow access to the HTTPS port.

Hmm, option D looks like the correct answer to me. The firewall-cmd command allows you to add the HTTPS service permanently and reload the firewall configuration.
