安装步骤

Install steps

像手机应用一样完成首次配置

Set it up like a mobile app

选择平台

从下载页选择 Android APK、Windows、macOS、iOS 或 Linux 对应文件，避免混用安装包。

确认来源

检查文件名、版本说明和下载域名，确保快连VPN下载链接来自官方下载地址。

开启权限

首次连接时系统会提示 VPN 配置权限，只在客户端内确认，不需要额外打开未知页面。

测试线路

用延迟测试判断网络状态，连接失败时先换线路，再检查本地代理或防火墙。

Pick platform

Choose the Android APK, Windows, macOS, iOS, or Linux file so the VPN installer matches your device.

Verify source

Review filename, version notes, and download host before using the LetsVPN official download link.

Allow permission

The first connection may ask for VPN configuration permission inside the app. Confirm it only from the installer flow.

Test route

Use latency checks first, then switch routes before changing local firewall or proxy settings.

隐私与安全

Privacy and security

把权限解释清楚，降低误操作

VPN configuration

Required to create the encrypted tunnel; without it, the app may fail or reconnect repeatedly.

连接排障

Troubleshooting

把“连不上”拆成可检查的四件事

Break connection failure into four checks

安装包是否正确

如果安卓设备安装失败，请确认使用快连VPNAPK；Windows 不应打开 macOS DMG，Linux 需要执行 RUN 文件权限。

系统权限是否允许

系统 VPN 配置未允许时，客户端可能停在连接中。重新打开应用并确认权限，通常不需要卸载。

本地网络是否拦截

公共网络、公司网络或本地代理可能影响连接。先关闭其他代理，再用延迟测试确认线路。

版本是否过旧

旧版本可能无法匹配新的线路策略。前往快连VPN下载官网核对最新安装文件。

Correct installer

Android needs the LetsVPN Android APK; Windows should use EXE, macOS should use DMG, and Linux may need executable permission for RUN.

System permission

If VPN permission is denied, the app may stay in a connecting state. Reopen the app and confirm permission before reinstalling.

Local network blocks

Public Wi-Fi, office networks, or another proxy may interfere. Disable competing proxy tools and test latency again.

Old version

An outdated VPN installer may not match the latest route policy. Use the LetsVPN official website download page to verify files.
