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

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

• The location menu will solely show regions, but each region includes hundreds of 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 be assigned to a different server.
• You can repeat this process until you find a server that suits your requirements.

Typical reasons for network problems include:

• Slow internet speeds in your area (when not using a VPN)
• High user demand at specific VPN server locations

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

• Verify your local internet speed by temporarily turning off the VPN
• Explore various network connections such as WiFi, 4G, or 5G with the VPN disabled to pinpoint any connection issues. For instance, if your WiFi connection is unstable, consider switching to a mobile data connection.
• Disable the VPN, select a new server location, and reconnect
• If you wish to remain connected to the same geographic area, disconnect and reconnect as this may connect you to a different server within the same locale.
• Keep performing these tests until you determine the best server for your needs.

Global Mode: This configuration enables VPN for all internet activities, which might lead to slower performance for local websites and applications.

Split Mode: This setting employs VPN solely for sites restricted by geographic barriers, like Google, YouTube, and Netflix, while allowing access to local networks for Chinese websites.

You can modify the routing mode in the App Settings.

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