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

To streamline the experience, we now only show regions. Heibao will automatically connect you to the top-performing server in your chosen region. Here are the details:

• The location menu will exclusively show regions, but each region consists of numerous servers. Once you select a region, Heibao automatically connects you to the server that delivers the best performance according to your network conditions.
• If you're unhappy with the server you are connected to, you can disconnect and reconnect to the same region to be assigned to a different server.
• You can continue this process until you find a server that suits your requirements.

Common reasons for network problems include:

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

To address these issues, you can attempt the following methods:

• Verify your local internet speed by temporarily turning off the NPV
• Test various network connections like WiFi, 4G, or 5G with the NPV disabled to identify any connection issues. For instance, if your WiFi is unstable, consider switching to mobile data.
• Disable the NPV, choose a different server location, and then reconnect
• If you prefer to remain connected to the same geographical area, try disconnecting and reconnecting, as this may connect you to a different server within the same region.
• Continue performing these tests until you find the best server suited for your needs.

Global Mode: This option enables NPV for all online activities, which might slow down local websites and applications.

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

You can adjust the routing mode in the App Settings.

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