    Check Your Internet Connection

    The most common reason you get a OneDrive error 0x8004de40 is that your internet connection isn’t working. Your connection may have stopped working, causing OneDrive not to establish a link to the cloud.

    Add OneDrive to Your Firewall’s Safelist

    In this case, turn off the real-time protection in your antivirus app and see if that resolves your issue. If your issue persists, uninstall your antivirus program and see if that fixes the problem.

    Reset OneDrive on Your Windows PC

    1. Open Run by pressing Windows + R.
    2. Type the following in the Run box and press Enter:
