Unresponsive Host

The host has open ports but does not respond to HTTP requests.

Severity: Low

What does this mean?

The host has one or more open ports but does not respond to HTTP requests on port 80 or 443. The server may be misconfigured, overloaded, still starting up, or running a non-HTTP service on those ports.

Why this is a problem

An endpoint that is reachable but not serving may indicate a broken deployment, or a service that should not be exposed to the internet at all. Either way, it is worth confirming that the host is behaving as intended rather than leaving an unexplained open port in your inventory.

What you should do

  • Confirm the service is meant to be publicly reachable
  • Check that the web server is running and healthy
  • If it is a non-HTTP service, confirm that exposing it is intentional
  • If the host has been retired, remove the DNS records pointing at it
