To ensure connectivity, the following steps should be taken:

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

We've observed that some users have difficulty selecting a server after choosing a region.

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

• The location menu will exclusively show regions, though each region has hundreds of servers. Upon choosing a region, Heibao will automatically link you to the server that delivers the best performance based on your network conditions.
• If you are not pleased with the server to which you are connected, you have the option to disconnect and then reconnect to the same region to be linked to a different server.
• You can keep repeating this process until you discover a server that fits your requirements.

Frequent reasons for network problems include:

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

To address these issues, consider trying the following approaches:

• Assess 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 detect any connection issues. For instance, if your WiFi is inconsistent, switch to a mobile data connection.
• Disable the NPV, select a new server location, and then reconnect
• If you prefer to remain within the same geographical area, disconnect and reconnect as this may connect you to an alternative server in the same region.
• Repeat these tests until you identify the most appropriate server for your needs.

Global Mode: Enabling this option activates NPV for all online activities, which could result in slower performance for local websites and applications.

Split Mode: This option utilizes NPV exclusively for sites that are restricted by geographic limitations, like Google, YouTube, and Netflix, while preserving local network access for Chinese websites.

You can modify the routing mode in the App Settings.

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