Okta displays an error during the login process when network configurations block access to the Okta Content Delivery Network (CDN). Resolving this issue requires allowing access to Okta IP addresses and enabling browser cookies. When navigating to the Okta login screen, the following error message appears:

Your OneDrive version is not supported

• Okta Identity Engine (OIE)
  
• Single Sign-On

Network configurations block access to the Okta CDN. This restriction prevents the login page from loading, triggering the error page.

Please try the following troubleshooting steps:

1. Allow access to the Required Okta domains as detailed in Allow access to Okta IP addresses.
2. Verify that cookies are enabled in the web browser.
