How Partial Blocking Works
Traffic filtering equipment (TSPU) analyzes the structure of transmitted data in real time. If the system detects a standard VPN tunnel signature, it lets the connection handshake through but completely blocks payload traffic and DNS requests.
How to Restore Access
- Change the protocol in the app: standard WireGuard and OpenVPN are blocked first; choose protocols with camouflage mimicking regular web traffic (VLESS, Reality, Hysteria2).
- Switch location or server: blocks are frequently applied to specific IP pools.
- Enable built-in DNS leak protection or manually configure third-party DNS servers in your connection settings.
