Backup Fails on System State: E3250 Error interacting with the cluster 1

[bonorad1]

Trying to backup the System State on one node in a cluster. I get an Error E3250 "Error interacting with cluster. (EC=RPC S Server Unavailable)"

This happens on both nodes. Running active-active. The user is a domain account, local admin, has the appropriate user rights (log on as a service, log on locally, act as part of operating system).

Everything else backs up successfully.

Anyone see this before?
What am I forgetting to do?

1-are you doing a backup using the node name or clsuter name?
2-Are you able to backup normal files other than system state?

1. Node Name.
2. Yes.

I can also browse to the Virtual Cluster Name and Group Names (I am running active/active) and back up all files on the cluster shares successfully.

Issue resolved. The problem was that Microsoft Firewall Client was installed on both Nodes of the cluster. With it enabled, the jobs were failing. Once disabled, the System State backups completed successfully.
