As of 2026, even the most dependable VPN can sometimes encounter issues in China. However, this does NOT imply that the service is entirely nonfunctional — often, it simply indicates that: your IP address, server, or protocol has been momentarily restricted by the Great Firewall (GFW).
Below are 5 clear indicators that your VPN is facing a block, along with effective solutions to regain quick access.
Indicator 1: Stuck on “Connecting…” for over 20 seconds
This typically suggests:
- The IP address of the server is restricted;
- The protocol has been identified;
- The connection port is undergoing filtering.
Solution:
- Change to an alternative region (Japan, Korea, Singapore);
- Change the protocol (TLS, WS, TCP/443);
- Restart the application.
Indicator 2: Connection successful, but foreign sites won’t load
This indicates DNS tampering or route restrictions.
- Google fails to load;
- YouTube freezes;
- ChatGPT cannot be reached;
- Local sites function properly.
Solution:
- Activate built-in DNS (DoH/DoT);
- Turn off ISP DNS;
- Utilize SmartDNS mode;
Indicator 3: Slow speeds exclusively during 8–11 PM
This reveals that the network is overloaded and the firewall is more stringent during busy hours.
Solution:
- Switch nodes prior to peak hours;
- Opt for low-latency routes in Asia;
- Enable obfuscation for added privacy.
Indicator 4: Operates on 4G/5G but fails on WiFi
Public and hotel WiFi often restrict encrypted protocols.
Solution:
- Use your mobile phone’s hotspot;
- Activate WebSocket/TLS mode;
- Steer clear of public networks.
Indicator 5: A server that was once stable suddenly malfunctions
The GFW regularly updates its blacklist. It’s not unusual for some IPs to be abruptly restricted.
Solution:
- Switch to backup servers;
- Attempt different protocols;
- Restart your connection.
Additional Indicator: Elevated packet loss
Symptoms include:
- Webpages taking over 10 seconds to load;
- Images loading incompletely;
- Videos stuttering at very low resolutions.
Solution:
- Utilize load-balancing routes;
- Select Asia nodes;
- Enable smart routing capabilities.
How to minimize the risk of being blocked
- Implement obfuscation;
- Avoid remaining on one server for extended periods;
- Frequently update your server list;
- Refrain from using free tools;
- Do not maintain idle connections for hours on end.
Final Thoughts
If your VPN ceases to function in China, it generally indicates that the IP or protocol has faced temporary blocking. By employing the appropriate strategies, you can swiftly regain access. For ongoing stability, Nice VPN List provides solid obfuscation and routing optimized for China.
