# Couldn't Link Device – WhatsApp QR Code or Pairing Code Fails

If you see the error **"Couldn't link device. Try again later"** when connecting your WhatsApp number to a Whapi.Cloud channel, it typically means the WhatsApp client is unable to complete the secure linking process. This can happen with both **QR code** and **pairing code (OTP)** methods.

#### 🔧 Troubleshooting Steps

Try the following tips — in most cases, they resolve the issue:

* **Update your WhatsApp app** to the latest version from the App Store or Google Play.
* **Disable any VPN** on your phone — it may interfere with WhatsApp’s authentication.
* **Check your phone’s time settings** and make sure they match your time zone. Enable automatic time if possible.
* If you're trying to connect via **pairing code (OTP)**, try using the **QR code method** instead — it is more stable.
* **Clear the WhatsApp app cache** on your phone (for Android users).
* If the issue still occurs, **reinstall WhatsApp** — this often solves pairing errors.

> In most cases, retrying after a short delay or following the steps above will resolve the issue.
