The split mode feature in Yafu NPV for China accommodates web applications such as Telegram, WhatsApp, or Gmail that operate using HTTPS. This mode is capable of modifying the routing for both HTTP (port 80) and HTTPS (port 443), thereby enabling access to the web versions of these applications. Nevertheless, the application versions might use different ports.

To guarantee access, the following actions should be taken:

• Select the "Global Mode" option in the routing settings.
• Adjust the application’s proxy settings. For instance, here is how you can update the proxy settings for the LINE app:
  
  

• If you try to sign in on a new device and go beyond the device limit, you'll be directed to the "Unbind Device" page, allowing you to remove any linked devices.

We have observed that some users find it difficult to select a server after they choose a region.

To make this easier, we now only show regions. Heibao will automatically connect you to the highest-performing server in your selected region. Here are the details:

• The location menu will display only regions, but each region includes hundreds of servers. When you pick a region, Heibao will automatically connect you to the server that provides the best performance based on your network conditions.
• If you are unhappy with the server you are connected to, you can disconnect and reconnect to the same region to connect to a different server.
• You can continue this process until you find a server that suits your requirements.

Typical reasons for network problems include:

• Slow local internet speeds (without utilizing a NPV)
• Increased user traffic at specific NPV server sites

To address these issues, you may consider the following approaches:

• Verify your local internet speed by temporarily turning off the NPV
• Experiment with various network connections such as WiFi, 4G, or 5G with the NPV disabled to pinpoint any connectivity issues. For instance, if your WiFi is unstable, switch to a mobile data connection.
• Disable the NPV, select a new server location, and reconnect
• If you prefer to remain connected to the same geographical region, disconnect and reconnect, as this may connect you to a different server within that area.
• Continue these trials until you locate the best server that meets your needs.

Global Mode: Enabling this setting activates NPV for all online activities, which might cause local websites and applications to run slower.

Split Mode: This option employs NPV solely for websites that are restricted due to geographic limitations, like Google, YouTube, and Netflix, while allowing local network access for Chinese sites.

You can modify the routing mode in the App Settings.

If you encounter difficulties accessing specific websites or apps, consider switching to "Global Mode."
