To guarantee access, the following steps 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 to change the proxy settings for the LINE app:

We have observed that some users find it challenging to select a server after choosing a region.

To streamline the process, we now only show regions. Heibao will automatically connect you to the best 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 select a region, Heibao will automatically connect you to the server that provides the best performance according to your network conditions.
• If you are not happy with the server you are connected to, you can disconnect and reconnect to the same region to link to a different server.
• You can continue this process until you find a server that suits your requirements.

Frequent causes of network problems are:

• Slow internet speeds in your area (without utilizing an NPV)
• Elevated user traffic at specific NPV server locations

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

• Assess your local internet speed by temporarily turning off the NPV
• Experiment with various network connections like WiFi, 4G, or 5G with the NPV disabled to pinpoint any connection issues. For instance, if your WiFi is inconsistent, try using 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 an alternative server within the same region.
• Keep performing these tests until you identify the most appropriate server for your needs.

Global Mode: This option enables NPV for all online activities, which could result in slower performance for local websites and applications.

Split Mode: This option applies NPV only to sites that are restricted due to geographical limitations, such as Google, YouTube, and Netflix, while allowing local network access to Chinese websites.

You can modify the routing mode in the App Settings.

If you encounter difficulties accessing specific websites or applications, try switching to "Global Mode."
