In 2026, even the most dependable VPN can sometimes encounter issues in China. This does NOT imply that the service is malfunctioning — in most cases, it simply indicates that: your server, IP, or protocol has encountered a temporary blockage due to the Great Firewall (GFW).
Here are 5 definitive indicators that your VPN is being blocked, along with effective solutions to quickly regain access.
Indicator 1: Stuck on “Connecting…” for over 20 seconds
This typically signifies:
- The server IP has been restricted;
- The protocol has been identified;
- The connection port is undergoing filtering.
Solution:
- Change to a different location (e.g., Japan, Korea, Singapore);
- Switch protocols (TLS, WS, TCP/443);
- Restart the application.
Indicator 2: Successfully connected, but international sites won’t load
This suggests DNS interference or route disruptions.
- Google fails to load;
- YouTube is unresponsive;
- ChatGPT cannot be accessed;
- Local websites operate without issues.
Solution:
- Activate built-in DNS (DoH/DoT);
- Disable your ISP's DNS;
- Utilize SmartDNS feature;
Indicator 3: Slow performance only between 8–11 PM
This indicates network congestion AND stricter firewall rules during peak times.
Solution:
- Switch nodes before peak hours;
- Opt for low-latency routes in Asia;
- Enable obfuscation mode.
Indicator 4: Works on mobile data but fails on WiFi
Public and hotel WiFi networks often block encrypted connections.
Solution:
- Utilize your phone's hotspot;
- Enable WebSocket/TLS settings;
- Avoid using public networks.
Indicator 5: A previously functioning server suddenly stops operating
The GFW frequently updates its block lists. It's common for certain IP addresses to be suddenly restricted.
Solution:
- Switch to backup nodes;
- Experiment with different protocols;
- Restart your connection.
Additional Indicator: Significant packet loss
Symptoms include:
- Webpages taking over 10 seconds to load;
- Images loading incompletely;
- Videos stuck at very low quality.
Solution:
- Employ load-balancing routes;
- Select nodes in Asia;
- Activate smart routing.
Ways to minimize blocking chances
- Utilize obfuscation;
- Avoid using the same server for extended periods;
- Regularly update your server list;
- Steer clear of free tools;
- Avoid leaving idle connections active for multiple hours.

If your VPN ceases to function in China, it generally indicates a temporary block on the IP or protocol. By applying the right tactics, you can quickly regain access. For consistent performance, Mobile VPN List provides excellent obfuscation and routing optimized for China.
