The split mode feature in Kuainiu NPV for China accommodates web applications such as Telegram, WhatsApp, or Gmail that employ HTTPS. This mode can modify the routing for both HTTP (port 80) and HTTPS (port 443), enabling access to the web versions of these applications. However, the app versions may utilize various other ports.

To guarantee access, the following actions should be taken:

• Select the "Global Mode" option found in the routing settings.
• Adjust the proxy settings of the application. For instance, here is how to change the proxy settings for the LINE app:
  
  

• If you try to log in from a new device and surpass the device limit, you will be directed to the "Unbind Device" page, allowing you to disconnect any linked devices.

We've observed that some users find it challenging to select a server after they have chosen a region.

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

• The location menu will display only regions, each of which contains many servers. When you select a region, Heibao will automatically connect you to the server that provides the best performance according to your network conditions.
• If you're unhappy with the server you're connected to, you can disconnect and reconnect within the same region to be assigned a different server.
• You can continue this process until you find a server that suits your requirements.

Frequent causes of network problems consist of:

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

To address these problems, you can attempt the following strategies:

• Assess your local internet speed by temporarily deactivating the NPV
• Explore various network connections like WiFi, 4G, or 5G with the NPV disabled to pinpoint any connection issues. For instance, if your WiFi connection is unstable, you might switch to mobile data.
• Disable the NPV, select a different server location, and then reconnect
• If you prefer to remain linked to the same geographic area, disconnect and reconnect, as this might connect you to another server within the same vicinity.
• Continue performing these tests until you identify the most appropriate server for your needs.

Global Mode: Enabling this option activates NPV for all online activities, which may result in slower performance for local websites and applications.

Split Mode: In this mode, NPV is utilized only for sites that are restricted by geographic limitations, like Google, YouTube, and Netflix, while still allowing access to local networks for Chinese websites.

You can modify the routing mode in the App Settings.

If you encounter difficulties accessing certain websites or applications, consider switching to "Global Mode."
