Windows Login Error

HandshakeException: Handshake error in client

This error usually happens when the Trusted Root certificates on your Windows machine are outdated.

To update the Trusted Root Certificates on Windows, you can use the certutil command. Here are the steps to do so:

1. Open Command Prompt as Administrator:

   • Press Windows + X and select Command Prompt (Admin) or Windows PowerShell (Admin).

2. Run the following command to update the root certificates:

   certutil -generateSSTFromWU roots.sst
   

   This command will generate a file named roots.sst that contains the latest root certificates from Windows Update.

3. Install the new root certificates:

   certutil -addstore -f ROOT roots.sst
   

   This command will add the certificates from the roots.sst file to the Trusted Root Certification Authorities store.

4. Clean up: After the installation, you can delete the roots.sst file if you no longer need it:

   del roots.sst
   

Make sure to restart your application after updating the certificates to ensure the changes take effect.

If the above steps don't resolve the issue, please follow this guide to update your trusted root certicates, and try again.
