In 2026, even the most dependable VPN can sometimes experience issues in China. This does NOT imply that the service is malfunctioning — typically, it just indicates: your server, IP address, or protocol has been temporarily restricted by the Great Firewall (GFW).
Below are 5 unmistakable indicators that your VPN is facing a blockage, along with actionable solutions to regain access swiftly.
Indicator 1: Stuck on “Connecting…” for over 20 seconds
This often suggests:
- The server IP has been blocked;
- The protocol has been identified;
- The connection port is under filtering.
Solution:
- Change to a different region (Japan, Korea, Singapore);
- Alter the protocol (TLS, WS, TCP/443);
- Restart the application.
Indicator 2: Successfully connected, but cannot access foreign websites
This indicates possible DNS poisoning or route obstruction.
- Google fails to load;
- YouTube freezes;
- ChatGPT is inaccessible;
- Local websites function normally.
Solution:
- Activate built-in DNS (DoH/DoT);
- Turn off ISP DNS;
- Switch to SmartDNS mode;
Indicator 3: Slow performance between 8–11 PM
This indicates a congested network AND stricter firewall measures during peak hours.
Solution:
- Change nodes before peak periods;
- Utilize low-latency routes in Asia;
- Enable obfuscation.
Indicator 4: Functions on 4G/5G but not on WiFi
Hotels and public WiFi often restrict encrypted protocols.
Solution:
- Use your mobile’s hotspot;
- Activate WebSocket/TLS mode;
- Avoid public networks.
Indicator 5: A once reliable server suddenly becomes unresponsive
The GFW regularly updates its block lists. It's common for specific IPs to be blocked abruptly.
Solution:
- Switch to backup nodes;
- Experiment with various protocols;
- Reconnect.
Additional Indicator: Significant packet loss
Signs include:
- Webpages take over 10 seconds to load;
- Images load partially;
- Videos are stuck at very low resolution.
Solution:
- Utilize load-balancing routes;
- Select Asia nodes;
- Enable smart routing.
Tips to minimize blocking risks
- Employ obfuscation;
- Avoid remaining on a single server for extended periods;
- Regularly update your server list;
- Steer clear of free tools;
- Avoid leaving inactive connections open for hours.
