Resolving the Secure Connection Failed Error
Let's dive into the potential solutions:

1. Restart the application and check your internet connection: Sometimes, a simple restart is all you need to resolve the issue. Ensure your internet connection is stable and restart OneDrive to see if the problem persists.
2. Check your firewall and antivirus settings: Ensure your firewall is not blocking OneDrive's access to the internet. You may also need to check your antivirus settings, as some software may be interfering with OneDrive's functionality.
