However, the application versions may operate on different ports.

To ensure proper access, the following steps should be taken:

• Enable the "Global Mode" option found in the routing settings.

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

To streamline the experience, we now show only 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 choose a region, Heibao automatically connects you to the server that delivers the best performance based on your network conditions.
• If you're not happy with the server you're connected to, you can disconnect and reconnect to the same region to connect to a different server.
• You can continue this process until you discover a server that suits your requirements.

Frequent reasons for network problems include:

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

To address these issues, consider trying the following methods:

• Assess your local internet speed by temporarily disabling the NPV
• Experiment with various network connections such as WiFi, 4G, or 5G with the NPV turned off to detect any connection issues. For instance, if your WiFi is spotty, switch to a mobile data connection.
• Disable the NPV, choose a different server location, and then reconnect
• If you prefer to stay within the same geographical area, disconnect and reconnect, as this may connect you to a different server in the same vicinity.
• Keep conducting these tests until you discover the most appropriate server for your needs.

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

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

You can adjust the routing mode in the App Settings.

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