Always on-Cluster service on primary node was down- Failed to bring secondary node as primary
Errors from node 2 (Secondary replica)
Cluster node XYZ was removed from the active failover cluster membership. The Cluster service on this node may have stopped. This could also be due to the node having lost communication with other active nodes in the failover cluster.
Cluster resource 'xyz_AG' of type 'SQL Server Availability Group' in clustered role 'xyz_AG' failed.
