"NSX Version found is not compatible with this global manager" error during Local Manager Federation Onboarding

Products

• VMware NSX

Issue/Introduction

• When attempting to add an NSX Local Manager to an NSX Global Manager, the "Check version compatibility" operation fails with the following error message:
  • "NSX version found is not compatible with this global manager"
    
• This occurs despite both managers running identical builds.

Environment

• VMware Cloud Foundation 9.0.x
• VMware NSX 9.0.x

Cause

• The incorrect certificate thumbprint (e.g., an individual node API thumbprint instead of the cluster VIP thumbprint) may have been provided during the Add New Location process.
• The resulting trust validation failure is incorrectly parsed by the system, resulting in a misleading version compatibility error.
  • This (the misleading error) is a known issue that will be resolved in a future release.

Resolution

1. Open an SSH session to the NSX Local Manager appliance and authenticate as the admin user.
2. Execute the following command to retrieve the correct thumbprint:
   

   1. get certificate cluster thumbprint

3. Copy the returned SHA-256 thumbprint.
4. Return to the Global Manager UI or API and re-attempt adding the Local Manager using the copied cluster VIP thumbprint.
