Issue/Introduction

While deploying supervisor the ,  the deployment fails with no route to host failure. 

Reviewing the log /var/log/vmware/wcp/wcpsvc.log the following error can be found

025-10-21T11:15:14.027Z error wcp [licensemonitor/license_event_monitor.go:257] [opID=licenseRefreshMonitor] Supervisor control plane failed: No connectivity to API Master: connectivity ok, config status ERROR

Environment

vCenter 8

Cause

HA proxy is not configured with frontend subnet that is different than the subnet used by the supervisor. 

by design the HA proxy frontend end point needs to be on its own subnet

Resolution

Apply the following configuration changes, 

• Configure the HA proxy to use a subnet like the following
  
  example 192.6.1.1/24
• with the supervisor using the following subnet 
  
  example 192.6.2.1/24
  
  
  
• Any subnet range is valid provided both the HA proxy and supervisor are on their own subnet.
