WhatsApp Web Not Working? Every Fix, Problem by Problem

Last updated: October 25, 2026

The short answer: most WhatsApp Web problems come from a weak internet connection or the browser. Reload web.whatsapp.com, check your internet, use an up-to-date browser, and clear the browser’s cache and cookies. If it logged you out by itself, open WhatsApp on your phone (it needs to be used at least every 14 days) and link the computer again. Find your exact problem below for the full fix.

Start here: three quick checks

1. Is it the real site? The address bar must say exactly web.whatsapp.com. Copycat pages “don’t work” because they’re fakes.
2. Is the computer online? Open any other website. If that fails too, the problem is your internet, not WhatsApp.
3. Is WhatsApp working on your phone? Open it and send yourself a test message. Your phone should also have been used for WhatsApp in the last 14 days, or linked devices are logged out.

WhatsApp Web won’t load, or the page is blank

1. Reload the page.
2. Use a supported browser. WhatsApp Web works on the latest versions of Chrome, Firefox, Microsoft Edge, Opera and Safari. It doesn’t work on some older browsers, including Internet Explorer. Update your browser if it’s out of date.
3. Clear the browser’s cache and cookies, then open web.whatsapp.com again. Your browser’s help pages show how.
4. Try a private/incognito window. If it works there, an extension (such as an ad or script blocker) is probably the cause. Turn extensions off one by one to find it.
5. Restart the computer. WhatsApp suggests turning the device off, waiting 30 seconds, and turning it back on.

“Computer not connected” or messages won’t send

WhatsApp says a poor internet connection is the most common reason for problems sending and receiving chats or uploading and downloading photos and videos. A yellow icon next to Computer not connected means the computer may not have an active internet connection.

1. Check the computer’s internet. If there’s no connection at all, contact your internet provider.
2. Refresh the page, then log out of WhatsApp Web and log back in.
3. Try another network. Office and university Wi-Fi sometimes blocks WhatsApp. Switch to a different Wi-Fi network or a phone hotspot.
4. If you manage the network, WhatsApp says to set it to let traffic to web.whatsapp.com and .whatsapp.net through.

WhatsApp Web keeps logging out

A linked computer gets logged out when:

• Your phone hasn’t used WhatsApp for more than 14 days. Open WhatsApp on your primary phone regularly to keep linked devices connected.
• The computer wasn’t used for 30 days. WhatsApp disconnects inactive linked devices automatically.
• The browser’s data was cleared, for example by a cleaning tool, a private window, or a browser set to delete cookies when it closes.
• Someone logged it out from the phone in Linked devices.

The fix is to link the computer again. If you didn’t log it out and none of the reasons above fit, check the Linked devices list on your phone for anything you don’t recognise: see how to check if someone is using your WhatsApp Web.

Can’t log in, or the QR code won’t scan

• Scan from inside WhatsApp (Linked devices > Link a device), not your camera app.
• You can link up to four devices. If you already have four, log one out first.
• No camera? Use Log in with phone number and enter the 8-character code on your phone instead.

Calls don’t work

WhatsApp is rolling out calling on WhatsApp Web gradually, so call buttons may not have reached your account yet. If they’re there but nobody can hear you, allow the microphone and camera for web.whatsapp.com in your browser and in your computer’s privacy settings.

Some features are missing

That may be normal. WhatsApp says viewing live location and creating or viewing broadcast lists aren’t supported on linked devices. Use your phone for those.

Frequently asked questions

Does my phone need to be on for WhatsApp Web to work?

No. Linked devices work even when your phone is off. But WhatsApp logs them out if you don’t use WhatsApp on your phone for more than 14 days.

Why does WhatsApp Web work at home but not at the office?

Office, school and university networks sometimes block WhatsApp. Try a hotspot, or ask the network administrator to allow web.whatsapp.com and .whatsapp.net.

Will clearing cookies delete my chats?

It logs WhatsApp Web out in that browser, but your chats stay on your phone and come back when you link the computer again.

Does WhatsApp Web work in Internet Explorer?

No. Use the latest Chrome, Firefox, Microsoft Edge, Opera or Safari.
