I have an environment consisting of DAG and Exchange. I keep getting this error even though I haven't set up a cluster. What could be causing this problem and how can I fix it?

[#2]

An Exchange DAG is built using a subset of Windows Failover Clustering services, so it will be related to that.

[#3]

@Dan_Snape that is, if I don't have a cluster, I have to create a cluster again, how can I solve the error. I should note that everything is working without problems at the moment

Description:
Cluster node 'DAG' 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. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapters on this node. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.

Have you done anything to the node that might cause it to go offline or not be contactable?
