Environment

VMware HCX

Cause

This is failing due to some stale entries for the appliance in HCX DB.

WORKAROUND:
If no migrations are currently in progress, you may deploy a new Service Mesh instance with the same service appliance type. Please ensure that the new appliance selects an IP address different from the one referenced in the error log.

If the appliance is a Network Extender you can remove the affected instance by reducing the number of NEs in the Service Mesh configuration: this will clean up the stale records and then allow increasing their number back to the original value in the Service Mesh, deploying a new replacement NE in the current version of HCX.
