Testing local network capabilities via STUN...
When you enter a URL, the app connects to public WebTorrent matchmaking servers. It sends an encrypted hash of your room name. If someone else is looking for the same room, the server introduces you. Because these public servers handle millions of users globally, this process relies on DNS, TCP, and TLS negotiation, and can occasionally take up to 8 seconds to process.
The Secure QR completely bypasses public matchmaking servers. It takes your local IP address, port, and security keys, compresses them into a 100-byte binary payload, and displays them on screen. The scanning device reads the pixels and connects instantly directly to your device (often remaining entirely on your local Wi-Fi).
Note: To keep the QR code small enough to be scanned by a camera, "TURN Relay" fallback candidates are deleted from the code. Therefore, Secure QR may fail if both devices are strictly on cellular data networks that require a server relay to punch through the carrier's firewall.
