Wildfly cluster's failover functionality doesn't work as expected

Following are the testing scenarios we did and the outcome:-

1. Network disabling on a VM for testing failover – Not working for both Linux and Windows environment.
2. Power off of a VM using VMware client for testing failover – Is working on Linux environment but not working on windows environment.
3. Ctrl + C method to stop services on a node for testing failover – works on both linux and windows environment
4. Stopping server running on Node /VM using Admin Console for testing failover - works on both linux and windows environment.

Jgroups subsystem configuration in domain.xml we have is below:-
