Hi,

I would like to check that apart from the error message, do you get any issue on the cluster, is there any cluster resource offline?

Please try to run Cluster validation on the cluster, check if there's any error or warning?

The event 2050 and 2051 is cluster diagnostic log, if we have any issue on the cluster, please try to find if there's any related "System" event log or "failover-cluster-operation" log.
