HTTP Connection Error
Unable to establish a connection to the web endpoint.
Severity: Warning
What does this mean?
DNS Watchdog resolved the DNS record to an IP address and attempted to connect to the web server, but the connection failed entirely. The server did not respond — there was no HTTP response at all, not even an error page.
Why this is a problem
A connection error means the web server is either not running, not listening on the expected port (80 or 443), or is blocked by a firewall. If a DNS record points to a host that does not serve web traffic, it may indicate abandoned infrastructure or a misconfiguration. Users and automated systems that try to reach this domain will experience timeouts.
What you should do
- Verify whether a web server is supposed to be running on this host
- Check that the web server process is running and listening on the correct ports
- Review firewall rules to ensure web traffic is not being blocked unintentionally
- If no web server is needed, consider removing the DNS record or updating it
