 - unable to find valid certification path to requested target

Environment

Cloud Director 10.x

Cause

This issue can occur if there is a trailing forward slash (/) at the end of the NSX ALB url configuration in Cloud Director. During the edge deletion attempt an extra forward slash is appended which results in a double forward slash (//) in the name.

Resolution

To resolve this matter ensure there is not a trailing forward slash (/) at the end of the NSX ALB url configuration.

To validate this:

1. Login to the Cloud Director provider portal.
2. Navigate to "Infrastructure Resources" -> "NSX-ALB" -> "Controllers"
3. Inspect the URL of the controller and remove the trailing forward slash from the end.
