How to Fix OneDrive Error 0x8004de44

If you encounter OneDrive Error Code 0x8004de44, you are facing a network connectivity block that prevents the desktop app from establishing a handshaking session with Microsoft’s authentication servers. This error is most commonly triggered by network routing proxies, particularly authenticated proxies (proxies requiring a username and password), which the Microsoft OneDrive client does not support.

This troubleshooting guide walks you through the causes and steps to resolve this error on both Windows and macOS.

What Causes OneDrive Error 0x8004de44?

This sign-in failure typically occurs when the local sync client’s web requests are intercepted. Key triggers include:

  1. Authenticated Proxy Configurations: OneDrive cannot prompt users for proxy credentials, meaning any proxy requiring a manual login blocks the app.
  2. Strict Corporate Firewalls or VPNs: Deep packet inspection (DPI) or corporate firewalls blocking WebSocket and SSL tunnels on port 443.
  3. Stale DNS Resolution Cache: The OS resolving outdated IP addresses for Microsoft login services.
  4. Corrupt Local Settings: Local OneDrive client settings holding incorrect network connection properties.

Detailed Steps to Resolve Error 0x8004de44

Platform-Specific Steps for Windows Users

Method 1: Reset System HTTP Proxy via Netsh

If a proxy was set globally at the system WinHTTP level, it might be bypassing standard GUI toggles. You can reset it using the command prompt.

  1. Open Command Prompt as Administrator.
  2. Type the following command and press Enter: 
    netsh winhttp reset proxy
  3. Restart your computer.

Method 2: Disable Settings Proxy

Ensure that the Windows user-level proxy is turned off:

  1. Press Windows Key + I to open Settings.
  2. Navigate to Network & internet > Proxy.
  3. Under Manual proxy setup, click Set up next to Use a proxy server, and toggle it Off.
  4. Enable Automatically detect settings under the Automatic proxy setup section.

Method 3: Reset the OneDrive App Config

Clear out local network parameters cached inside the application:

  1. Press Windows Key + R to open the Run window.
  2. Copy, paste, and run: 
    %localappdata%\Microsoft\OneDrive\onedrive.exe /reset
  3. Wait 2 minutes, then launch OneDrive manually.

Platform-Specific Steps for macOS Users

Method 1: Disable System Proxies in Network Settings

macOS systems must be configured to bypass active HTTP/HTTPS proxy interceptions.

  1. Click the Apple logo (top-left) and choose System Settings > Network.
  2. Select your active network connection (e.g., Wi-Fi or Ethernet) and click Details.
  3. Click on the Proxies tab.
  4. Disable Web Proxy (HTTP) and Secure Web Proxy (HTTPS).
  5. Click OK to apply the configuration.

Method 2: Reset Network Proxies via Terminal

For users who prefer using command-line interface tools, you can disable proxies on the Wi-Fi interface directly:

  1. Open Terminal (located in /Applications/Utilities/).
  2. Run the following commands (replace "Wi-Fi" with "Ethernet" if you are using a wired connection): 
    sudo networksetup -setwebproxy "Wi-Fi" "" 0 off
sudo networksetup -setsecurewebproxy "Wi-Fi" "" 0 off

Method 3: Clear Keychain Items and plist Configs

Purge corrupted local credentials that might block reconnection:

  1. Open Terminal and execute: 
    killall OneDrive
defaults delete com.microsoft.OneDrive-mac
rm -rf ~/Library/Containers/com.microsoft.OneDrive-mac
  2. Relaunch OneDrive and sign in again.

Summary Checklist for Quick Reference

  • Reset the system WinHTTP proxy settings to default using the netsh command.
  • Disabled “Use a proxy server” in Windows or macOS proxy settings.
  • Disconnected from any active corporate VPN client to test the direct connection.
  • Flushed the local system DNS resolver cache.
  • Reset the local OneDrive desktop client using the /reset terminal command.
