How to Fix OneDrive SSL_Error_No_Cypher_Overlap Error on Windows 11: Complete Troubleshooting Steps

If you use OneDrive on Windows 11, you might sometimes encounter the SSL_Error_No_Cypher_Overlap error. This error usually happens due to issues with secure connections between your device and OneDrive servers.

It can prevent you from syncing files or accessing your OneDrive cloud storage properly. Fortunately, there are several ways to fix this issue.

This guide will walk you through simple, step-by-step troubleshooting methods to resolve the error. You do not need advanced technical skills to follow along.

By the end, your OneDrive should work smoothly again without connection errors.

Quick Note Before You Start

  • Make sure your Windows 11 system is fully updated. Updates often fix security and network issues.
  • Check your internet connection to ensure it is stable and working.
  • Verify that your date and time settings are correct, as SSL relies on accurate system time.
  • Close OneDrive completely before starting any fixes — right-click the OneDrive icon in the system tray and select “Close OneDrive.”

Step 1: Restart Your Computer and OneDrive

Sometimes, a simple restart can clear temporary glitches that cause SSL errors. Restarting your PC refreshes network settings and system processes.

  1. Click the Start menu and select “Restart.”
  2. After rebooting, open OneDrive again from the Start menu or system tray.
  3. Check if the error still appears when syncing files.

If the problem persists, move on to the next step.

Step 2: Check Date and Time Settings

SSL connections depend on your system’s date and time to verify certificates. If your clock is wrong, OneDrive may reject the connection.

  1. Right-click the time in the bottom-right corner and select “Adjust date/time.”
  2. Make sure “Set time automatically” is turned on.
  3. If it is on but the time is still incorrect, toggle it off and then back on.
  4. If needed, click “Sync now” under “Additional settings” to update the time immediately.

Try OneDrive again to see if the error is resolved.

Step 3: Clear SSL State in Windows

Clearing the SSL cache can fix corrupted or outdated SSL certificates causing errors.

  1. Press Win + R to open the Run dialog.
  2. Type inetcpl.cpl and press Enter to open Internet Properties.
  3. Go to the Content tab.
  4. Click the Clear SSL state button.
  5. Click OK and close the window.
  6. Restart OneDrive and check if it connects properly.

Step 4: Update Windows and OneDrive

Outdated software can cause compatibility and security issues. Updating both Windows and OneDrive can solve many problems automatically.

  1. Open Settings from the Start menu.
  2. Go to Windows Update and click Check for updates.
  3. Install any available updates and restart your PC if prompted.
  4. To update OneDrive: open Microsoft Store, click on your profile icon, select Downloads and updates, and click Get updates.

Step 5: Reset OneDrive

If OneDrive’s internal settings are corrupted, resetting it can fix SSL errors without losing your files.

  1. Press Win + R to open the Run dialog.
  2. Type the following command and press Enter:
    %localappdata%MicrosoftOneDriveonedrive.exe /reset
  3. Wait a few minutes for OneDrive to reset and restart automatically.
  4. If OneDrive does not start, open it manually from the Start menu.

This step often resolves deeper software issues.

Step 6: Check Your Firewall and Antivirus Settings

Sometimes, security software blocks OneDrive’s secure connections, causing SSL errors. You need to ensure OneDrive is allowed through your firewall and antivirus.

  1. Open Windows Security from the Start menu.
  2. Go to Firewall & network protection.
  3. Select your active network and click Allow an app through firewall.
  4. Find Microsoft OneDrive in the list and make sure it is allowed on both private and public networks.
  5. Also check your antivirus software settings to whitelist OneDrive if needed.

Advanced Option: Use Command Prompt to Check TLS Settings

OneDrive requires modern TLS protocols for secure connections. Disabling older protocols or enabling newer ones in Windows can help.

  1. Open Command Prompt as Administrator (search for “cmd,” right-click, and choose “Run as administrator”).
  2. Type the following commands one by one and press Enter after each:
    reg add "HKLMSYSTEMCurrentControlSetControlSecurityProvidersSCHANNELProtocolsTLS 1.2Client" /v Enabled /t REG_DWORD /d 1 /f
    reg add "HKLMSYSTEMCurrentControlSetControlSecurityProvidersSCHANNELProtocolsTLS 1.3Client" /v Enabled /t REG_DWORD /d 1 /f
  3. Restart your computer and try using OneDrive again.

This ensures your system supports the latest encryption standards required by OneDrive.
