Open Port Checker
Verify if a TCP port on an external IP or domain is open through server-side TCP connection testing.
Enter a host and port number above, then click [Check Port].
Port Checker Usage & Troubleshooting Guide
This tool initiates an active TCP SYN connection from the AurumTools server to the target host and port to determine if it is reachable from the public internet.
If a port shows closed or timeout, inspect server daemon listening status, Docker port mappings, host firewalls (ufw/iptables), and router port-forwarding configs.
