If your device is connected to the internet with a strong signal, please try the following steps to resolve the issue :
- Refresh the WhatsApp Web page.
- Clear your browser’s cache and cookies. For detailed instructions, visit your browser’s support website.
- Log out of WhatsApp Web and log back in.
- Uninstall and reinstall WhatsApp. You can learn how to download WhatsApp Desktop from the official site.
- Restart your device. Turn it off, wait about 30 seconds, then turn it back on.
- Check your network connection. Some office or university Wi-Fi networks may cause issues. Try switching to another Wi-Fi or use a mobile hotspot.
- Adjust your network settings. Ensure your network allows traffic to _web.whatsapp.com_ and _.whatsapp.net_, as blocked connections can prevent WhatsApp from working properly.
