This mode can adjust the routing for both HTTP (port 80) and HTTPS (port 443), allowing access to the web versions of these applications. However, the application versions might use different ports.

To guarantee access, the following steps should be taken:

• Enable the "Global Mode" option found in the routing settings.
• Adjust the proxy settings of the application. For instance, here’s how to update the proxy settings for the LINE app:
  
  

• If you try to sign in on a new device and go over the device limit, you'll be directed to the "Unbind Device" page where you can disconnect any linked devices.

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

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

• The location menu will display only regions, each of which contains numerous servers. When you choose a region, Heibao will automatically connect you to the server that delivers 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 keep repeating this process until you find a server that suits your requirements.

Common reasons for network problems include:

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

To address these problems, you can consider the following actions:

• Verify 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 spot any connection issues. For instance, if your WiFi connection is inconsistent, switch to mobile data instead.
• Disable the NPV, choose a different server location, and then reconnect
• If you wish to remain in the same geographical area, disconnect and reconnect, as this might connect you to another server in the same region.
• Keep performing these tests until you identify the best server that meets your needs.

Global Mode: Enabling this option activates NPV for all online activities, which might hinder the performance of local websites and applications.

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

You can modify the routing mode in the App Settings.

If you experience difficulties accessing specific websites or applications, consider switching to "Global Mode."
