The split mode feature in Jianguo NPV for China accommodates web applications such as Telegram, WhatsApp, and Gmail that rely on 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. Nonetheless, the application versions may operate on a variety of other ports.

To guarantee access, the following actions should be taken:

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

• Should you try to log in on a new device and surpass the device limit, you will be redirected to the "Unbind Device" page, allowing you to detach any linked devices.

We've observed that some users have difficulty selecting a server after picking a region.

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

• The location menu will exclusively show regions, but each region hosts hundreds of servers. When you choose a region, Heibao will automatically connect you to the server that provides optimal performance based on your network conditions.
• If you’re unhappy with the server you're connected to, you can disconnect and reconnect to the same region to be matched with a different server.
• You can continue this process until you find a server that suits your needs.

Frequent reasons for network problems include:

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

To address these issues, consider trying the following solutions:

• Verify your local internet speed by temporarily turning off the NPV
• Experiment with various network connections such as WiFi, 4G, or 5G while the NPV is disabled to pinpoint any connection issues. For instance, if your WiFi is inconsistent, switch to a mobile data network.
• Deactivate the NPV, select a new server location, and then reconnect
• If you prefer to remain connected to the same geographical area, disconnect and reconnect, as this may connect you to a different server within the same region.
• Keep conducting these tests until you discover the best server for your needs.

Global Mode: Enabling this setting activates NPV for all online activities, which might hinder the performance of local websites and apps.

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

You can modify the routing mode in the App Settings.

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