In 2026, even the most dependable VPN can sometimes encounter issues in China. This doesn’t indicate a failure of the service — most often, it signifies: your server, IP address, or protocol has been momentarily restricted by the Great Firewall (GFW).
Here are five unmistakable indicators that your VPN is facing a block, along with effective solutions to regain access swiftly.
Indicator 1: Stuck on “Connecting…” for over 20 seconds
This typically signifies:
- The server's IP may be restricted;
- The protocol has been identified;
- The connection port is under filtration.
Solution:
- Change to a different location (Japan, Korea, Singapore);
- Switch the protocol (TLS, WS, TCP/443);
- Restart the application.
Indicator 2: Successfully connected, yet foreign sites won’t load
This indicates DNS tampering or route obstruction.
- Google fails to load;
- YouTube is unresponsive;
- ChatGPT is inaccessible;
- Local sites function correctly.
Solution:
- Activate integrated DNS (DoH/DoT);
- Turn off ISP DNS;
- Utilize SmartDNS mode;
Indicator 3: Slow speeds between 8–11 PM only
This shows that the network is overloaded AND the firewall is more stringent during rush hours.
Solution:
- Change nodes ahead of peak hours;
- Use low-latency routes in Asia;
- Enable obfuscation.
Indicator 4: Functions on 4G/5G but not on WiFi
Public and hotel WiFi often restrict encrypted protocols.
Solution:
- Utilize your phone’s hotspot;
- Activate WebSocket/TLS mode;
- Steer clear of public networks.
Indicator 5: A previously reliable server suddenly fails
The GFW regularly modifies its blocklists. It’s common for certain IPs to be unexpectedly blocked.
Solution:
- Switch to backup nodes;
- Experiment with different protocols;
- Restart the connection.
Additional Indicator: Significant packet loss
Symptoms:
- Web pages take longer than 10 seconds to load;
- Images load partially;
- Videos freeze at a very low resolution.
Solution:
- Utilize load-balancing routes;
- Choose Asia nodes;
- Enable smart routing.
Tips to minimize the likelihood of being blocked
- Utilize obfuscation;
- Avoid staying connected to a single server for extended periods;
- Regularly update your server list;
- Steer clear of free services;
- Avoid leaving idle connections active for hours.
