如果不先扫描二维码，您将无法使用 WhatsApp Web(cannot use WhatsApp Web)（即您的WhatsApp帐户的基于浏览器的扩展程序）。(WhatsApp)本指南将重点介绍 WhatsApp(WhatsApp)的Web QR码无法在您的浏览器中加载的原因。您还将了解为什么您的手机有时无法扫描计算机上的二维码。
更重要的是，您将学习解决这些WhatsApp Web 二维(WhatsApp Web QR)码问题的八种可能方法。
如何使用 WhatsApp 网页二维码
如果您在访问WhatsApp Web时遇到困难，可能是因为您扫描的二维码不正确。
值得一提的是，WhatsApp的二维码仅适用于(WhatsApp)WhatsApp内置的扫描仪。使用第三方扫描仪扫描WhatsApp QR码或(WhatsApp QR)使用您的相机应用程序作为 QR 码扫描仪(using your camera app as a QR code scanner)不会将即时通讯程序连接到您的浏览器。
确保您在 WhatsApp 的“设置”(Settings)菜单中使用 QR 码扫描仪。
对于 iOS 设备，启动WhatsApp，进入设置(Settings)>链接设备(Linked Devices)，然后点击链接设备(Link a Device)。
在Android上，打开WhatsApp，点击右上角的三点菜单图标，选择Linked devices，然后选择Link A Device。将屏幕上的二维码与WhatsApp扫描仪的取景器对齐，然后等待您的浏览器建立连接。
请注意，二维码会在 20 秒后更改。另外，连接到WhatsApp Web有一个超时期限。如果您在两分钟内没有扫描任何二维码，则必须重新加载页面或在屏幕上选择单击以重新加载二维码(Click to Reload QR code)以显示新的二维码。
为什么你不能扫描WhatsApp Web的二维码(QR Code)？
在所有条件相同的情况下，WhatsApp Web在 99% 的时间内加载 QR 码没有任何问题。但是，网络连接不佳、网络浏览器问题、应用程序或扩展程序冲突、浏览器不兼容等可能会阻碍WhatsApp 网络二维(WhatsApp Web QR)码的加载。
我们应该提到，如果相机镜头脏了或二维码的一部分被覆盖，您的设备将无法获得清晰的二维码图像。用干的超细纤维布擦拭设备的后置摄像头镜头。我们还建议您擦拭计算机屏幕。
接近(Proximity)度是另一个需要考虑的重要因素。确保(Make)您的设备距离代码不太近或太远。如果 QR 码在您的设备上不起作用，我们将重点介绍另外八种故障排除解决方案。
1. 检查您的互联网连接
如果您的 Internet 连接速度较慢或您的计算机间歇性断开 Internet 连接，您的浏览器可能无法加载 QR码( dropping its internet connection)。
尝试在同一浏览器中访问其他网站。如果浏览器没有加载其他网页，您的互联网连接可能有问题。
检查是否有活动的互联网连接。在Windows PC 上，转至设置(Settings)>网络和 Internet(Network & Internet) >状态(Status)。
对于 macOS 驱动的台式机和笔记本电脑，前往系统偏好设置(System Preferences)>网络(Network)并检查左侧边栏中网络类别的连接状态。
2.检查手机的连接
您的手机和电脑必须有互联网连接才能使用WhatsApp 网页版(WhatsApp Web)。两个设备不一定必须在同一个网络上。当您扫描 QR 码时， WhatsApp(WhatsApp)将无法在没有互联网连接的情况下在您的计算机上打开。
确保您的手机或平板电脑已通过蜂窝数据或Wi-Fi连接到互联网。对于 iOS 设备，请确认WhatsApp可以在后台访问您设备的蜂窝数据。
转到设置(Settings)，选择WhatsApp，然后打开蜂窝数据(Cellular Data)。
3. 关闭或重新加载 WhatsApp 网页
这个简单的操作是另一个值得尝试的有效故障排除解决方案。如果WhatsApp Web QR码未显示在您的浏览器中，请按F5或地址栏中的刷新图标(refresh icon)。如果问题仍然存在，请关闭选项卡（在 Windows 中按Ctrl + W或在 macOS中按Command + W ）并在新选项卡中再次加载WhatsApp Web 。
4.关闭未使用的标签
如果您在浏览器中运行的活动选项卡过多，可能会降低您的互联网连接速度。关闭您不需要的选项卡，暂停正在进行的下载，以及在后台消耗带宽的其他活动。
重新加载(Reload)WhatsApp(WhatsApp Web)网页，检查这次二维码是否正确加载。
5. 终止VPN或代理(Proxy)连接
WhatsApp 没有针对 VPN(WhatsApp isn’t optimized for VPN)或代理服务进行优化。如果您的设备上有这些连接或配置，请禁用它们并重新加载WhatsApp Web。这适用于一些WhatsApp Web QR 码未(WhatsApp Web QR code didn’t load up)在浏览器中加载的Windows用户。
6. 清除 WhatsApp 网页缓存
损坏(Corrupt)的临时文件或缓存文件可能会破坏WhatsApp Web的性能。前往(Head)浏览器的 cookie 或数据管理部分，删除之前由WhatsApp（或WhatsApp Web）创建的临时文件。
对于 Chrome，请转到设置(Settings)>隐私和安全(Privacy and security)> Cookie 和其他站点数据(Cookies and other site data)>查看所有 cookie 和站点数据(See all cookies and site data)。在搜索栏中输入“(Type “) web.whatsapp.com”或“whatsapp.com”，然后点击Bin 图标(Bin icon)或选择删除所有显示(Remove All Shown)以删除与WhatsApp Web或WhatsApp本身相关的所有 cookie。
请按照本指南清除任何浏览器上的缓存以(guide on clearing cache on any browser)获取详细说明。如果在清除所有相关 cookie 和数据后仍无法加载 QR 码，请重置您的浏览器设置或尝试使用其他浏览器。
7. 更新您的浏览器
WhatsApp 建议(WhatsApp recommends)使用最新版本的Google Chrome、Mozilla Firefox、Microsoft Edge、Safari或Opera来使用WhatsApp Web。使用过时的浏览器或未提及的其他网络浏览器可能会导致某些WhatsApp 网络(WhatsApp Web)功能无法使用。WhatsApp Web不支持所有版本的Internet Explorer。
8.禁用你的广告拦截器
广告拦截软件有时会阻止 WhatsApp Web 二维码加载(stops the WhatsApp Web QR code from loading)。禁用您计算机上安装的任何广告拦截浏览器扩展程序(ad-blocking browser extension)或应用程序，然后重新加载WhatsApp(WhatsApp Web)网页。
如果问题仍然存在，请重新启动浏览器或计算机（禁用广告拦截器）并尝试加载 QR 码。
联系 WhatsApp Messenger 支持
如果这些建议都没有解决问题，请联系 WhatsApp支持。(Support)在手机上打开 WhatsApp(Open WhatsApp)，前往设置(Settings)>帮助(Help)>联系我们(Contact Us)并在对话框中描述问题。或者，在您的浏览器中访问WhatsApp 支持(WhatsApp Support)页面，提供您的联系方式，在“您如何使用WhatsApp？”中选择Web 和桌面。(Web and Desktop)部分。
(Describe)在对话框中描述问题并发送消息。请务必提供有关您为解决问题而采取的故障排除步骤的详细信息。
WhatsApp Web QR Code Not Working? 8 Fixes to Try
You cannot use WhatsApp Web (i.e., the browser-based extension of your WhatsApp account) without first scanning a QR code. This guide will highlight reasons why WhatsApp’s Web QR code fails to load in your browser. You’ll also learn why your phone sometimes fails to scan the QR code on your computer.
More importantly, you’ll learn eight possible ways to resolve these WhatsApp Web QR code problems.
How to Use WhatsApp Web QR Code
If you’re experiencing difficulties accessing WhatsApp Web, it could be because you’re scanning the QR code incorrectly.
It’s worth mentioning that WhatsApp’s QR code only works with the scanner built into WhatsApp. Scanning the WhatsApp QR code with a third-party scanner or using your camera app as a QR code scanner won’t connect the instant messenger to your browser.
Ensure you’re using the QR code scanner in WhatsApp’s Settings menu.
For iOS devices, launch WhatsApp, go to Settings > Linked Devices and tap Link a Device.
On Android, open WhatsApp, tap the three-dot menu icon in the top-right corner, select Linked devices, and select Link A Device. Align the QR code on the screen with the WhatsApp scanner’s viewfinder and wait for your browser to establish the connection.
Note that the QR code changes after 20 seconds. Plus, there’s a timeout period for connecting to WhatsApp Web. If you don’t scan any QR code within two minutes, you’ll have to reload the page or select Click to Reload QR code on the screen to bring up new QR codes.
Why Can’t You Scan QR Code for WhatsApp Web?
All things being equal, WhatsApp Web loads the QR code 99% of the time without any issue. However, poor internet connection, problems with your web browser, conflicting apps or extensions, browser incompatibility, etc., can hinder the WhatsApp Web QR code from loading.
We should mention that your device won’t get a clear image of the QR code if the camera lens is dirty or if a section of the QR code is covered. Wipe your device’s rear-facing camera lens with a dry microfiber cloth. We also advise wiping your computer’s screen.
Proximity is another important factor to consider. Make sure your device isn’t too close or too far from the code. We highlight eight more troubleshooting solutions to try if the QR code isn’t working on your device.
1. Check Your Internet Connection
Your browser may fail to load the QR code if your internet connection is slow or your computer is intermittently dropping its internet connection.
Try visiting other websites within the same browser. If the browser doesn’t load other web pages, your internet connection may be a problem.
Check if there’s an active internet connection. On a Windows PC, go to Settings > Network & Internet > Status.
For macOS-powered desktops and notebooks, head to System Preferences > Network and check the connection status for the network categories on the left sidebar.
2. Check Your Phone’s Connection
Your phone and computer must have an internet connection to use WhatsApp Web. Both devices don’t necessarily have to be on the same network. WhatsApp won’t open on your computer without an internet connection when you scan the QR code.
Ensure your phone or tablet is connected to the internet either via cellular data or Wi-Fi. For iOS devices, confirm that WhatsApp has access to your device’s cellular data in the background.
Go to Settings, select WhatsApp, and toggle on Cellular Data.
3. Close or Reload WhatsApp Web
This simple action is another effective troubleshooting solution worth trying. If the WhatsApp Web QR code doesn’t show up in your browser, press F5 or the refresh icon in the address bar. Should the problem persist, close the tab (press Ctrl + W in Windows or Command + W in macOS) and load WhatsApp Web again in a new tab.
4. Close Unused Tabs
If you’re running too many active tabs in your browser it can slow down your internet connection. Close tabs you don’t need, suspend ongoing downloads, and other activities consuming bandwidth in the background.
Reload the WhatsApp Web page and check if the QR code loads correctly this time.
5. Terminate VPN or Proxy Connections
WhatsApp isn’t optimized for VPN or proxy services. If you have these connections or configurations on your devices, disable them and reload WhatsApp Web. That’s worked for some Windows users whose WhatsApp Web QR code didn’t load up in their browsers.
6. Clear WhatsApp Web Cache
Corrupt temporary or cache files can disrupt WhatsApp Web’s performance. Head to your browser’s cookie or data management section and delete the temporary files previously created by WhatsApp (or WhatsApp Web).
For Chrome, go to Settings > Privacy and security > Cookies and other site data > See all cookies and site data. Type “web.whatsapp.com” or “whatsapp.com” in the search bar and tap the Bin icon or select Remove All Shown to delete all cookies relating to WhatsApp Web or WhatsApp itself.
Follow this guide on clearing cache on any browser for detailed instructions. Reset your browser’s settings or try a different browser if the QR code still doesn’t load despite clearing all related cookies and data.
7. Update Your Browser
WhatsApp recommends using the latest version of Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, or Opera to use WhatsApp Web. Using an outdated browser or other web browsers not mentioned may render some WhatsApp Web features unusable. WhatsApp Web doesn’t support all versions of Internet Explorer.
8. Disable Your Adblocker
Ad-blocking software sometimes stops the WhatsApp Web QR code from loading. Disable any ad-blocking browser extension or app installed on your computer and reload the WhatsApp Web page.
If the problem persists, restart your browser or computer—leaving the adblocker disabled—and try loading the QR code.
Contact WhatsApp Messenger Support
Reach out to WhatsApp Support if none of these recommendations resolved the problem. Open WhatsApp on your phone, head to Settings > Help > Contact Us and describe the issue in the dialog box. Alternatively, visit the WhatsApp Support page in your browser, provide your contact details, select Web and Desktop in the “How do you use WhatsApp?” section.
Describe the problem in the dialog box and send the message. Be sure to provide details about troubleshooting steps you’ve taken to fix the issue.
