    You're running into a fairly common OneDrive for Business connectivity issue — Error 0x8004de40 means:

    “OneDrive is having trouble connecting to the internet.”

     

    Try These Fixes in Order

    • Check Internet Options (TLS Settings)
    • Reset Winsock
    • Ensure OneDrive is Allowed Through Firewall
    • Disable IPv6 (as a Temporary Test)
    • Use OneDrive Troubleshooter
    • Fully Reset OneDrive Configuration
    • Check Internet Explorer Settings
    • Group Policy or Registry

     

    Still not working?

    • Test with a different network (e.g. mobile hotspot) → Could be DNS or firewall issue.
    • Try creating a new Windows user account, then try to set up OneDrive there.
    • Try using OneDrive Web (https://onedrive.live.com) temporarily until client works.
    • Contact your IT Admin if you're on an enterprise-managed device — they may have policies in place.

     

    Hope this helps you.
