Port Checker

Test one TCP port on one public hostname or IP address from this service's server environment.

What this result means

Open means one TCP connection succeeded from our server. Closed and timed-out results can reflect firewalls, routing, geographic access rules, or rate limits; they do not establish service health.

What to do next

For an open port, review DNS and IP details. For a closed or timed-out port, verify firewall, NAT, router, and DNS settings, then re-test from the intended client network.
