• Use "Global Mode" in routing settings
• Change the proxy settings of the app, below is an example of changing proxy settings for LINE:

To make it easier for you, we decide to show region only. Heibao Jiasuqi will automatically select the best performance server within your selected region for you. These are the details:

• Location list only shows the regions. Under the hood, there are hundreds of servers within each region. Upon selecting a region, Heibao Jiasuqi will connect you with the best performance server according to your network condition.
• If you don't like the connected server, you can always disconnect and re-connect to the same region, you will be connected to a different server.
• You can repeat above step until you are satisfied.

There are several common reasons:

• Slow local internet (without App on)
• Certain App server location has busy traffic

To troubleshoot the network issues, please follow the steps:

• Check your local network speed by disconnect the App;
• While keeping App disconnected, switch between WIFI, 4G, 5G to find the troubleshoot your network. E.g. if your wifi has poor connectivity, switch to your cellular 4G/5G.
• Disconnect App, switch to another region, and connect;
• If you like to stay in the same region, try disconnect and reconnect to the same region. Even you are selecting the same region, there are actually hundreds of servers behind a single region. Every time you connect, we will relocate a different server for you.
• You can repeat above steps until you find the best server for you.

Global Mode: Access everything with Heibao Jiasuqi App. This might slow down some local websites & apps traffic.

You can change the routing mode under App Settings.

If you found certain websites or apps can't be accessed, please change your routing mode settings to "Global Mode".

 这种情况大多是因为系统代理地址没有被正常设置成功，或是有第三方软件屏蔽和阻拦导致的，解决办法是我们需要再手动填写上黑豹加速器(Heibao)的科学上网代理地址。

请按如下步骤操作：

• 在windows系统中搜索“internet选项”并打开
• 继续点击“连接”标签页
• 继续点击右下方“局域网设置”按钮
• 在局域网(LAN)设置页的“使用自动配置脚本”处打√，并在下方地址处填入：http://127.0.0.1:7525/proxy
• 继续点击右下方“确定”，再点击“确定”关闭internet属性。
• 最后请完全关闭浏览器，再从新打开浏览器即可科学上网。

如下图：

Because of the nature of software (changing proxy settings), the anti-virus or firewall might consider it as a threat. During the installation, if you encounter any warning prompts, please choose "allow", "agree", "trust" or similar actions. Otherwise, Heibao Jiasuqi will not work as it couldn't gain access to change the proxy settings.

Using a Heibao Jiasuqi App on your Windows PC will ensure that everything you do is secure. By connecting to any of our server locations, you can replace your device‘s IP address with a different one, protect your data on unsecured Wi-Fi networks, and access censored sites and services.

While there are free Apps for Windows available, they can’t match a service like Heibao Jiasuqi, which provides optimized connections for superior speed, security, and stability, without any bandwidth caps. We keep your online traffic secure with strong encryption while offering 100+ global server locations to choose from. You’ll also have access to our 24/7 customer support via live chat and email.

It’s easy! Simply subscribe to Heibao Jiasuqi, download the app to your device, and press the “On” button on the screen.

While Windows 10 and 11 have a built-in client, it is technically not a service and still requires you to connect to a third-party like Heibao Jiasuqi. It’s also not easy to set up. So in most cases you are better off using the Heibao Jiasuqi app directly.

A Heibao Jiasuqi network, or virtual private network, when you connect to the internet is the best way to protect your privacy. In addition to encrypting your online activity and protecting your personal information from third-party interception, Heibao Jiasuqi can also help you defeat censorship by making you appear to be in a different country.
