What Causes Error 0x8004de40?

Error 0x8004de40 means OneDrive can’t connect to the cloud. Most of the time, it’s a network or configuration issue—not something wrong with your files. Here’s how you can troubleshoot it.

1. Check Your Internet Connection

First, make sure your device is actually online.

• Test your browser. Can you visit any websites?
• Try a different Wi-Fi network or connect with an Ethernet cable if possible.
• Restart your router. A quick reboot can fix a lot of network problems.

2. Change Internet Properties Settings

OneDrive relies on certain internet protocols. Here’s how to check your settings:

1. Press Windows + R, type inetcpl.cpl, and hit Enter.
2. In the Internet Properties window, go to the Advanced tab.
3. Scroll down and make sure TLS 1.0, TLS 1.1, and TLS 1.2 are all checked.
4. Click Apply and OK.

Restart your computer and try syncing OneDrive again.

3. Reset OneDrive

If you’re still getting the error, resetting OneDrive can help:

1. Press Windows + R.
2. Type %localappdata%\Microsoft\OneDrive\onedrive.exe /reset and press Enter.
3. OneDrive should restart automatically. If it doesn’t, open it manually from the Start menu.

4. Check Your Firewall and Antivirus

Sometimes, security software can block OneDrive.

• Temporarily disable your antivirus and firewall.
• Try syncing OneDrive.
• If it works, add OneDrive to your antivirus/firewall’s allowed apps.

5. Update OneDrive

Outdated software can cause sync errors.

• Go to the OneDrive download page and grab the latest version.
• Install it over your current version—no need to uninstall first.

6. Reset Network Settings

If nothing else works, try this:

1. Open Settings > Network & Internet > Status.
2. Click Network reset at the bottom.
3. Restart your PC.

Wrapping Up

OneDrive error 0x8004de40 is usually caused by network or settings problems. Try these steps in order, and you should be able to solve it without much hassle. If you’re still having trouble, consider reaching out to Microsoft Support.
