Resolution

Temporarily stopping the http service on the NSX Manager that currently owns the VIP will prompt a failover.
One of the other 2 NSX Managers will then be elected the HTTPS leader. This may take a few minutes to complete.

1. On the NSX Manager owning the VIP, ssh as admin and run
   #stop service http
2. UI or API requests directed directly at this node will no longer be served.
   Until the VIP fails over it will also be inaccessible.
3. Monitor for the HTTPS leader to change
   #get cluster status verbose
4. Confirm the NSX UI is again accessible via the VIP 
5. The http service can now be restarted on the NSX Manager
   #start service http
