Nevertheless, the application versions might 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 to modify the proxy settings for the LINE app:

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

To make things easier, 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 solely show regions, but each region is made up of hundreds of servers. When you choose a region, Heibao will automatically connect you to the server that provides the best performance based on your network conditions.
• If you're unhappy 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 find a server that suits your requirements.

Typical reasons for network problems include:

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

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

• Verify your local internet speed by temporarily turning off the NPV
• Experiment with various network connections such as WiFi, 4G, or 5G with the NPV disabled to detect 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 connect you to a different server within the same zone.
• Repeat these tests until you locate the best server to meet your needs.

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

Split Mode: This option only applies NPV to sites that are restricted due to geographical limitations, like 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're having difficulty reaching specific websites or applications, consider switching to "Global Mode."
