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

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

• The location menu will solely present 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’re not happy with the server you are linked to, you can disconnect and reconnect to the same region to be connected to a different server.
• You can continue this process until you find a server that satisfies your requirements.

Typical reasons for network problems consist of:

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

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

• Verify your local internet speed by temporarily turning off the NPV
• Experiment with different network connections like WiFi, 4G, or 5G with the NPV disabled to locate any connectivity issues. For instance, if your WiFi connection is unstable, try switching to mobile data.
• Disable the NPV, select a different server location, and reconnect
• If you wish to remain connected within the same geographical area, disconnect and reconnect, as this may link you to another server in the same region.
• Keep performing these tests until you discover the most appropriate server for your needs.

Global Mode: This configuration enables NPV for all online activities, which might impact the performance of local websites and applications.

Split Mode: This option utilizes NPV solely for sites that are restricted due to geographical limitations, such as Google, YouTube, and Netflix, while preserving local network accessibility for Chinese websites.

You can modify the routing mode in the App Settings.

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