One of the less talked about features of WhatsApp is Companion Mode or Multiple Devices, which allows users to link up to 4 additional devices to the WhatsApp account. Thanks to the companion mode, you can run your WhatsApp account independently on different phones.

However, to continue using WhatsApp on other devices, you must first link the devices to your WhatsApp account. Linking another device to a WhatsApp account is super easy, but sometimes, you may experience problems while scanning the QR code or during the linking process.

Recently, many users got an unusual error message while linking their devices to WhatsApp Web. The error message reads ‘WhatsApp web couldn’t link device’, preventing users from accessing their WhatsApp chats on PC.

Why you can’t link a device?

There could be various reasons for WhatsApp failing to link to a device. Below, we have mentioned a few obvious ones.

  • Your PC/Mobile has no or unstable internet.
  • You are using a VPN or Proxy app on your phone.
  • The WhatsApp app is outdated.
  • Bugs & Glitches in WhatsApp
  • Corrupted web browser cache.

So, if you get the same ‘WhatsApp Web Couldn’t Link Device’ error message and are stuck in the login screen, continue reading the guide. Below, we have shared some simple steps to fix ‘WhatsApp Couldn’t Link Device Try Again Later’ error. Let’s get started.

1. Make Sure Your Internet is Working

Check your Internet Connectivity

Like every other web-based service, WhatsApp web also needs an uninterrupted internet to link your device. The linking process is done entirely over the internet; hence, unstable internet connectivity can only lead to problems.

So, before you try the next methods, check if your internet is working and is stable. You can visit the website to check your internet speed.

Even if your internet is working, it’s recommended to reconnect to the WiFi network or Ethernet you’re currently connected to.

2. Restart the devices

If you are trying to link to WhatsApp web on a desktop from the mobile app but are constantly failing to do so, you need to restart both devices.

You need to restart your computer as well as your Android smartphone. Restarting will possibly rule out the bugs & glitches that may be preventing the WhatsApp services from functioning correctly.

So, restart both devices and then try to link again. If the problem persists, follow the next methods.

3. Disable the VPN or Proxy Apps

Security & Privacy apps like VPNs, Antivirus software, Firewalls, etc often conflict with incoming connections, leading to errors.

Using a VPN connection on mobile while linking to WhatsApp web (desktop) can delay the connection to the server, leading the login failed error.

So, if you are using any VPN/ Proxy or Firewall app on your mobile or desktop, it’s recommended to turn them off to properly establish a connection. Once turned off, try the Linked Devices feature of the WhatsApp mobile app to link the WhatsApp web account.

4. Check the WhatsApp App Permissions

If you have denied the permissions that WhatsApp asks for during the installation, you won’t be able to link devices. This is because WhatsApp needs multiple permissions to function properly, and if you’ve denied any of the permissions, you will face problems.

So, it’s important to check whether the required permissions are granted. Here’s what you need to do.

1. Tap & hold the WhatsApp app icon on your home screen and select App Info.
