Partial Filtering Mechanism on DPI Hardware
Handshakes for protocols like OpenVPN or WireGuard often occur over standard network ports, so the smartphone interface considers the session active. As soon as heavy data exchange begins, traffic analyzers detect the characteristic size and frequency of encrypted blocks, forcibly zeroing incoming speeds without physically tearing down the tunnel.
How to Restore Loading Speeds
- Switch your active protocol to VLESS, Trojan, or Hysteria2 in settings
- Try changing your port to secure web port 443
- Switch to a server in another location with a different IP range
- Check your DNS service status and enable DoH (DNS over HTTPS)
