​

Troubleshooting Common Issues

​

Devices Not Discovering Each Other

• Ensure both devices are on the same network

• Update to the latest browser version
• Clear browser cache and cookies
• Disable VPN or proxy services
• Try a different browser

• Check firewall settings
• Verify router doesn’t block peer-to-peer connections
• Try switching between WiFi and cellular data

​

Transfer Failures

• iOS devices have 200MB memory limits per transfer
• Break large files into smaller chunks
• Ensure sufficient available RAM

• WebRTC connections may drop on unstable networks
• Files can be resumed if transfer is interrupted
• Consider using WiFi for more stable connections

​

Performance Optimization

• Use modern browsers (Chrome/Edge recommended)
• Connect via WiFi rather than cellular data
• Close unnecessary browser tabs
• Ensure sufficient available memory

• 5GHz WiFi provides better performance than 2.4GHz
• Ethernet connections are most stable
• Avoid network congestion during large transfers
