As of 2026, even the most dependable VPN can occasionally encounter issues in China. This does NOT imply that the service is entirely nonfunctional — rather, it typically indicates: your IP address, server, or protocol has been momentarily blocked by the Great Firewall (GFW).
Here are 5 unmistakable indicators that your VPN is experiencing a block, along with effective solutions to regain access swiftly.
Indicator 1: "Connecting..." remains for over 20 seconds
This generally suggests:
- The IP address of the server is restricted;
- The protocol has been identified;
- The connection port is under filtration.
Solution:
- Change to a different region (Japan, Korea, Singapore);
- Switch protocols (TLS, WS, TCP/443);
- Restart the application.
Indicator 2: Successful connection, but overseas sites won’t load
This indicates either DNS pollution or route blocking.
- Google fails to load;
- YouTube is stuck;
- ChatGPT is unreachable;
- Local websites function properly.
Solution:
- Enable built-in DNS (DoH/DoT);
- Turn off ISP DNS;
- Utilize SmartDNS mode;
Indicator 3: Slow performance between 8–11 PM
This means congestion is present in the network AND the firewall becomes more restrictive during busy hours.
Solution:
- Switch nodes prior to peak times;
- Choose low-latency routes in Asia;
- Activate obfuscation.
Indicator 4: Functions on 4G/5G but not with WiFi
Public and hotel WiFi networks frequently block encrypted connections.
Solution:
- Utilize your mobile hotspot;
- Turn on WebSocket/TLS mode;
- Avoid using public networks.
Indicator 5: Formerly stable server suddenly stops functioning
The GFW often updates its blocking lists. It’s common for specific IPs to abruptly become restricted.
Solution:
- Switch to backup servers;
- Experiment with different protocols;
- Restart the connection.
Additional Indicator: High packet loss
Signs include:
- Webpages taking over 10 seconds to load;
- Images loading partially;
- Videos freezing at low resolutions.
Solution:
- Use routes that balance load;
- Select nodes in Asia;
- Enable intelligent routing.
How to decrease the likelihood of being blocked
- Use obfuscation;
- Avoid using the same server for extended periods;
- Frequently update your server list;
- Steer clear of free tools;
- Don’t keep idle connections active for long durations.
