Cannot access Compute Instance over Public IP (Port 80) - "No route to host"

İbrahim AlagözJul 28 2025

I deployed a Compute instance in Oracle Cloud Free Tier with a public IP. Apache is running and responds on http://localhost, and port 80 is listening.
Security Lists, NSG rules, and Internet Gateway seem configured correctly.
However, when accessing via public IP (curl http://[public-ip]) I get:
curl: (7) Failed to connect to [IP] port 80: No route to host

Any help?
