Environment

VMware Cloud Director Availability 4.x

Cause

This issue can occur when Cloud Director load balancer is not configured for SSL passthrough impacting authentication requests from the Cloud Replication Management Appliance.

Resolution

To resolve this issue, ensure the Cloud Director load balancer has SSL passthrough enabled. Once SSL passthrough is enabled, repair the Cloud Director in the Cloud Director Availability Provider Portal.

For more information, see the Configure to Accept a Renewed VMware Cloud Director Endpoint or Certificate section of the Cloud Director Availability documentation.

Additional Information

When Cloud Director's load balancer is not configured for SSL passthrough, this can also impact the functionality of the Cloud Director Availability plug-in.

For more information, see The Cloud Director Availability plug-in is not visible in the Cloud Director main menu in Cloud Director Availability 4.x.
