Can't access cluster info remotely

Can anyone tell me what happened.  I was able to access cluster information on remote servers and now I cannot.  

This used to work:  Get-ClusterNode $NodeEntered | Get-ClusterGroup

Now I get an error:

Get-ClusterNode : Failed to retrieve the node 'remoteNode' from the cluster 'currentNode'.
    An error occurred opening node 'remoteNode'.
    The cluster node was not found.

I have set my execution policy to remoteSigned.
