Port check from our server
The tool checks whether the specified TCP port is reachable from the perspective of our server. This is a useful test for diagnosing web services, email services, APIs, VPNs and other network services listening on a specific port.
Check the port
Enter the domain or IP address and TCP port number. The tool will try to establish a connection directly from our server.
What is Port check for?
Port check allows you to verify whether the service is listening on the specified TCP port and whether it is possible to connect to it from the perspective of our server.
You can check HTTP and HTTPS ports, mail service ports, API ports, monitoring system ports, administration panels or custom services running on the server or router.
If the port is open, the TCP connection should be established correctly. If it is closed, filtered by a firewall, or the host is not responding, the tool will show a connection error or timeout.
