About these checks & limitations
  • HTTPS checks use fetch(url, {mode:"no-cors"}); a ✅ means TCP/TLS connected (even if CORS hides the body). A ❌ often means DNS/route/TLS blocked.
  • TURN/STUN checks use WebRTC ICE. Finding an srflx candidate implies STUN reachability on that transport/port.
  • Browsers can’t open arbitrary ports. For deeper TCP/UDP tests, use admin tools/CLIs on the device or a lightweight helper service.
