However, the application versions may use various other ports.
To ensure access, the following measures should be implemented:

• Use the "Global Mode" option available in the routing settings.
• Modify the proxy settings of the application. For example, here is how you can change the proxy settings for the LINE app:

We've observed that some users have difficulty selecting a server after choosing a region.
To streamline the process, we now display only regions. Niuniu VPN for China will automatically connect you to the highest performing server within your designated region. Here are the details:

• The location menu will only list regions, but each region encompasses hundreds of servers. When you choose a region, Niuniu VPN for China will automatically connect you to the server that delivers the best performance based on your network conditions.
• If you're not satisfied with the server you're connected to, you can disconnect and reconnect to the same region to be linked to a different server.
• You can repeat this process until you find a server that meets your requirements.

• Slow internet speeds locally (without using a VPN).
• High user traffic at certain VPN server locations.

To resolve these issues, you can try the following methods:

• Check your local internet speed by temporarily disabling the VPN.
• Test different network connections such as WiFi, 4G, or 5G with the VPN off to identify any connection problems. For example, if your WiFi is unreliable, switch to a mobile data connection.
• Turn off the VPN, switch to a new server location, and then reconnect.
• If you want to stay connected to the same geographical area, disconnect and reconnect as this could link you to a different server within the same region.
• Continue these tests until you find the most suitable server for your requirements.

• You can view your redeemed plans in the "My Account" section once you've redeemed your points.
• For a referral to be successful, your referred friend must download and start using the app. If they download but do not use the app, you will not receive your referral point until they begin using it.
