The System Diagnostics window provides a quick overview of the current system status and helps verify that all required network components are configured correctly before establishing a connection.

The diagnostics panel includes the following checks:

Third-party Firewall

Verifies whether a third-party firewall is installed and active on the system. Third-party firewall software may interfere with incoming or outgoing network connections.

Application Firewall Rule

Checks whether the application has been granted permission to communicate through Windows Firewall. If the application is blocked, remote connections may not function correctly.

Server & Latency

Displays the currently selected server and performs a latency test. For the best performance, choose the server with the lowest available ping.

Port Forwarding (UPnP)

Checks whether the router supports UPnP (Universal Plug and Play) and whether the required port forwarding rule has been configured automatically. When successful, no manual router configuration is required.
