In 2026, even the most dependable VPN can sometimes experience issues in China. This does NOT imply that the service is entirely nonfunctional — rather, it often indicates that: your server, IP address, or protocol has faced a temporary block by the Great Firewall (GFW).
Here are five unmistakable indications that your VPN might be obstructed, along with effective methods to quickly regain access.
Indication 1: "Connecting..." remains for over 20 seconds
This typically suggests:
- The IP address is restricted;
- The protocol has been identified;
- The connection port is under scrutiny.
Solution:
- Change to a different region (Japan, Korea, Singapore);
- Alter the protocol (TLS, WS, TCP/443);
- Restart the application.
Indication 2: Successful connection, but foreign websites are inaccessible
This points to DNS tampering or route obstruction.
- Google fails to load;
- YouTube is stuck;
- ChatGPT is unreachable;
- Local websites function perfectly.
Solution:
- Activate the built-in DNS (DoH/DoT);
- Turn off ISP DNS;
- Utilize SmartDNS.
Indication 3: Slow performance between 8–11 PM only
This indicates that the network is overloaded AND the firewall enforces stricter measures during peak times.
Solution:
- Change nodes prior to peak hours;
- Opt for low-latency routes in Asia;
- Enable obfuscation.
Indication 4: Functional on 4G/5G but not on WiFi
Encrypted protocols are often blocked by hotel and public WiFi.
Solution:
- Use your mobile hotspot;
- Activate WebSocket/TLS mode;
- Avoid using public networks.
Indication 5: A previously reliable server ceases to work
The GFW frequently revises its blocklists, making it normal for certain IPs to be suddenly restricted.
Solution:
- Switch to alternate nodes;
- Experiment with different protocols;
- Restart the connection.
Additional Indication: Significant packet loss
Symptoms include:
- Webpages taking over 10 seconds to load;
- Images loading incompletely;
- Videos stalling at low resolutions.
Solution:
- Implement load-balancing routes;
- Select Asian nodes;
- Enable smart routing.
Ways to minimize the risk of being blocked
- Employ obfuscation;
- Avoid using a single server for extended periods;
- Regularly update the server list;
- Steer clear of free tools;
- Avoid leaving idle connections active for hours.
