How to Fix OneDrive Desktop Client Connection Error 2604
Question details
The user needs to resolve a network connection error preventing the desktop cloud storage client from synchronizing files.

- Product
- Microsoft OneDrive
- Device & OS
- Windows
- Scenario
- Attempting to sync local computer files to cloud storage using the desktop client.
- Observed behavior
- The desktop client displays a 'No Network Connection 2604' error and fails to sync, even though the web version functions normally and the network is active.
Verify that your computer has a stable internet connection and check the Microsoft 365 Service Health status page to ensure there are no ongoing server outages affecting cloud synchronization.
Restart and Reset the OneDrive Desktop Application
This is the most highly recommended method to clear corrupted local cache data and force the desktop client to re-establish a stable server connection.
Connection Error 2604 often occurs due to cached credentials or background glitches within the desktop app itself. By thoroughly restarting the app and utilizing the Windows Store reset command, you can clear these bottlenecks without losing any of your stored files.
Click the cloud icon in the Windows system tray (bottom right corner), click the gear icon for Settings, and select 'Quit OneDrive' to completely close the background process.
Click the Windows Start button, type 'OneDrive' into the search bar, and press Enter to launch the application again.
Press the Windows Key + R to open the Run dialog box. Type 'wsreset.exe' and press Enter. A blank Command Prompt window will open and automatically close after a few seconds.
Press the Windows Key + R again, paste '%localappdata%\Microsoft\OneDrive\onedrive.exe /reset' into the text box, and click OK. If you see a 'Windows cannot find' error, try pasting 'C:\Program Files\Microsoft OneDrive\onedrive.exe /reset' instead.
Open your web browser, log into your cloud storage account online, and click the 'Sync' button in the top menu to force the desktop client to wake up. Wait 5 to 10 minutes for the file processing to resume.

Test Alternative Networks and Windows Profiles
If resetting the client fails, isolate the issue by testing a different internet connection or user profile to bypass hidden firewall blocks or corrupted user registry keys.
Edit and Sync Documents Effortlessly with WPS Office
If persistent Microsoft OneDrive desktop errors disrupt your workflow, consider switching to WPS Office. It provides a lightweight, highly compatible alternative to Microsoft Office, featuring built-in cloud synchronization that operates smoothly without complex local client configurations.

Frequently Asked Questions
What causes the No Network Connection Error 2604?
Error 2604 is typically caused by corrupted local cache data, temporary Microsoft 365 server outages, or strict local firewall settings that block the desktop application from communicating with the authentication servers.
Will running the reset command delete my locally stored files?
No. Resetting the desktop client solely clears application settings and forces a fresh synchronization check. Your actual files, whether stored locally on your hard drive or in the cloud, will remain untouched.
How long does it take for synchronization to resume after a client reset?
It generally takes between 5 to 10 minutes for the client to scan existing folders and re-establish the connection. This duration can increase depending on your network speed and the total number of files in your directory.
