Summary: Calls fail to start or drop quickly.
What You Might Notice
- Calls won’t start or connect
- One-way audio or frequent drops
- Messaging apps show “connection error”
Most Common Cause
- A torrent/P2P app is running and creates many simultaneous connections, which can temporarily limit other traffic.
- Voice/video calls rely on external STUN/TURN/relay services to traverse networks; if your app can’t reach them, calls won’t establish reliably.
How to Fix
- Close all torrent/P2P and heavy background apps.
- Wait 10–15 minutes for connections to reset.
- Ensure your calling app can use external STUN/TURN/relay (most modern messengers do this automatically).
- Try again.
Still Having Issues?
- Test on another device or VPN location.
- Update the calling app to the latest version.
