Fusion 2704.1.23 - Server Verification Warning, HTTP 403 after successful sign-in, unable to access cloud services

[slava124678]

I have a problem with Autodesk Fusion 2704.1.23 on Windows 11 25H2 (Build 26200.8655).

Fusion starts normally and I can successfully sign in to my Autodesk account. The license is activated successfully.

Immediately after signing in, Fusion displays:

Server Verification Warning - Unable to validate a security certificate

If I click Trust Anyway, Fusion then shows:

Sorry, Fusion was unable to save sufficient data for offline mode and needs to go online.

Fusion cannot continue and cloud services are unavailable.

What I have already tried

• Complete reinstall of Fusion.
• Reinstall Autodesk Identity Manager.
• Reset Login State using Autodesk Licensing and Sign-in Helper.
• Created a new Fusion Team Hub.
• Tested with two different Autodesk accounts.
• Tested with two different Internet connections (home Wi-Fi and mobile hotspot).
• Updated Windows to the latest version.
• Verified and regenerated Windows root certificates.
• Microsoft Defender is the only antivirus installed.
• Autodesk Access reports no available updates.

Diagnostic information

Fusion logs show:

• Successful authentication.
• Successful license activation.
• Requests to Fusion Team endpoints fail with HTTP 403.
• Requests to:

fusionteam/login/v2/hubs

return 403 Forbidden, after which Fusion cannot retrieve Hub information or access cloud services.

Identity Manager appears to work correctly.

I have Fusion logs, Identity logs, and installer logs available and can upload them if needed.

Has anyone experienced this issue or knows how to resolve it?
