After you install DR backup agent on the Hyper-V host, it gets into the Waiting for pairing state, and waits 24 hours to receive the settings (password and port) from the Cloud Failover Appliance (CFA) to establish connection.
To establish connection between the DR backup agent on the Hyper-V host and the CFA:
In the CFA Management Console, go to Clients › Edit.
Find and select the client created for the Hyper-V host.
In the General group, click Push Client Settings.
The backup agent will receive the settings from CFA and get into the Paired state.
