How do I troubleshoot Nginx firewall issues?
To troubleshoot Nginx firewall issues, start by checking the firewall rules to ensure that the necessary ports are open.
What ports should I check for Nginx?
You should check ports 80 (HTTP) and 443 (HTTPS) to ensure they are open for incoming traffic.
How can I check if the ports are open?
You can use the command sudo ufw status on Ubuntu or iptables -L to check the status of your firewall rules.
What if the ports are closed?
If the ports are closed, you can open them using commands like sudo ufw allow 80 and sudo ufw allow 443.
