I disable the failover and re-enable it. Now the status changed to starting failover service(it's over 10 mins). Also, there's an even in primary node shows the failover completed. The primary node service is degraded and Communication links are failed. The failover status in secondary node are same as before. Maybe I need to wait a bit longer?

Info
Starting failover service on both nodes ... please wait.
