STATUS_PORT_UNREACHABLE
The destination port is unreachable
The host path may be reachable even though the destination port is not. Verify the exact transport protocol and port, listener state, and any ICMP or policy indication associated with the failure.
This is narrower than host unreachable. The host or route may exist, but the requested service endpoint is not reachable at that transport port.
What to inspect
- Verify destination port and listener state.
- Check firewall policy and ICMP port-unreachable responses.
- Do not replace this with DNS troubleshooting unless the address was wrong.
