Environment

VMware NSX-T Data Center 3.2.1

Cause

This issue can occur if credentials are incorrectly configured in the dry run tool.

Resolution

From VMware NSX-T Data Center 3.2.2 the VM based dry run tool is deprecated, upgrading to a later version would avoid this issue.

 

Workaround

• To reattempt running the dry run tool, a new instance of the VM needs to be deployed
• Ensure that the credentials for the NSX Manager are correct.
