The split mode feature in Haiou NPV for China accommodates web applications such as Telegram, WhatsApp, or Gmail that use 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 application versions may operate on different 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's how you can alter the proxy settings for the LINE app:
  
  

• Should you try to log in on a new device and go beyond the device limit, you will be redirected to the "Unbind Device" page, allowing you to disconnect any linked devices.
• Alternatively, you can go to "Menu" > "App Settings" > "Device List" to choose and unbind a device you prefer.

It's usual to misplace usernames or passwords, and we strive to simplify the recovery process. Here are your options:

• If you can't recall your username, please reach out to us and include a screenshot of your payment confirmation.
• If you've forgotten your password, simply utilize the "forgot password" option found in the app.

We have observed that some users have difficulty selecting a server after choosing a region.

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

• The location menu will now show only regions, but each region includes hundreds of servers. When you select a region, Heibao will automatically connect you to the server that provides optimal performance based on your network conditions.
• If you are not happy with the server you are connected to, you have the option to disconnect and reconnect to the same region to connect to a different server.
• You can repeat this process until you locate a server that fits your requirements.

Common reasons for network problems include:

• Local slow internet speeds (without using a NPV)
• Increased user traffic at specific NPV server locations

To address these issues, you might try the following approaches:

• Verify your local internet speed by temporarily disabling the NPV
• Test various network connections like WiFi, 4G, or 5G with the NPV off to spot any connection issues. For instance, if your WiFi is inconsistent, switch to a mobile data connection.
• Disable the NPV, choose a different server location, and then reconnect
• If you prefer to remain connected to the same geographic area, disconnect and reconnect, as this may link you to another server within the same region.
• Keep conducting these tests until you identify the most suitable server for your needs.

Global Mode: This option enables NPV for all online activities, which might cause local websites and applications to load more slowly.

Split Mode: This setting utilizes NPV solely for sites that are restricted due to geographic limitations, such as Google, YouTube, and Netflix, while preserving access to local networks for Chinese websites.

You can modify the routing mode within the App Settings.

If you encounter issues accessing specific websites or applications, consider switching to "Global Mode."
