WhatsApp Web Not Connecting — What Causes It & How to Fix It

What Does This Error Mean?

WhatsApp Web needs your phone to be connected to the internet — it mirrors your phone. If your phone goes offline, WhatsApp Web disconnects too. Refreshing the page and scanning the QR code again usually fixes it.

Affected Models

WhatsApp Web on Chrome
WhatsApp Web on Firefox
WhatsApp Web on Edge
WhatsApp Desktop

Common Causes

Your phone is not connected to the internet (WhatsApp Web mirrors the phone)
Browser cookies are blocked or have been cleared
The QR code expired before you could scan it
Too many linked devices — you've reached the 4-device limit
Browser extension interfering with WhatsApp Web

How to Fix It

Make sure your phone has an active internet connection.

WhatsApp Web doesn't work independently. Your phone must be online — on Wi-Fi or mobile data — at all times.
Refresh the WhatsApp Web page.

Press F5 or Ctrl+R in your browser to reload web.whatsapp.com. A new QR code will appear.
Scan the QR code quickly — it expires after about 20 seconds.

Open WhatsApp on your phone > tap the three dots (Android) or Settings (iPhone) > Linked Devices > Link a Device. Point your phone camera at the QR code on screen.
Try a different browser.

If Chrome isn't working, try Edge or Firefox. Browser extensions in Chrome sometimes block WhatsApp Web.
Clear browser cookies for whatsapp.com.

In Chrome: click the padlock icon in the address bar > Cookies > Remove cookies for whatsapp.com. Then refresh and scan again.

When to Call a Professional

If WhatsApp Web never stays connected despite your phone being online, try the WhatsApp Desktop app instead. Download it from whatsapp.com/download for a more reliable connection.
