Encounter a hidden firewall preventing access to a specific port
You're facing an issue where port 80 is only accessible via SSH (port 22), not for web traffic. This often happens when firewall rules or configuration settings are misaligned. Check the following: ensure your VNC ingress rule correctly forwards port 80 to the appropriate backend, verify that UFW allows port 80 if needed, and confirm the web server service is running. Also, review any application-level restrictions or logs for clues.
