Symptoms:
Error: " Operation: Configure Target Site Data-Flow Rules Failed. Reason: unable to post lwd configuration" is received while replicating a Virtual Machine (VM).

Resolution

The error indicates that the Target side Data Flow rules failed. ( Unable to Post lwd configuration )
It is recommended to re-initialize the Hybrid Cloud Extension (HCX) services. However, on doing this, the existing ongoing migrations/replications will be paused/lost briefly. 

On-Prem HCX manager services/Server, 

a. Log in to the VMware HCX Appliance Management interface: https://<hcx-ip-or-fqdn>:9443.
b. Navigate to Appliance Summary. (-->Configuration-> restart - Application Mgmt services )
c. All the services can be found to monitor or restart them. 

The only two services that are optional are the SNMP and SSH services. All others must always be running.
