Troubleshooting connection issues

1. QR Code Scanning Issues

If you are having trouble scanning the QR code to link your WhatsApp account, consider the following common triggers:

• QR Code Not Displaying: The code may fail to load due to browser caching or temporary network dropouts.
• QR Code Expires Quickly: For security reasons, WhatsApp QR codes expire every 10–15 seconds.
• Camera Focus/Quality: Your phone camera lens may be smudged, or the screen brightness on your computer may be too low.
• Scanning Stalls: The process hangs after scanning but does not redirect to the dashboard.

Solutions:

1. Refresh the Code: Click the "Refresh QR Code" button immediately if the code appears greyed out.
2. Check Connectivity: Ensure both your mobile phone and your computer have a stable internet connection.
3. Clean Your Camera: Wipe your phone's camera lens and ensure your computer screen brightness is turned up to 100%.
4. Manage Linked Devices: WhatsApp limits the number of active linked devices. Open WhatsApp on your phone, go to Linked Devices, and log out of unused sessions.
5. Force Restart: Force quit the WhatsApp application on your phone and refresh the WasenderApi dashboard page before trying again.

2. "Phone Offline" or Disconnection Errors

Even after a successful scan, your instance may disconnect if the phone loses communication with WhatsApp servers.

• Battery Saver Mode: Ensure your phone is not in "Low Power" or "Battery Saver" mode, which restricts background data.
• Background Data: Allow WhatsApp to use background data in your phone's settings.
• Connection Timeout: If the phone has been turned off or without internet for more than 14 days, the linked device session will expire automatically.
