Clustered Task giving RPC Server unavailable error

Hi everyone,

I have a clustered environment with SQL AlwaysOn. When I try to create a clustered task using powershell using this command, I get an error Register-ClusteredScheduledTask : The RPC server is unavailable.

Register-ClusteredScheduledTask–ClusterMyCluster–TaskNameMyResourceSpecificTask–TaskTypeResourceSpecific–ResourceMyResourceName–Action $action –Trigger $trigger

I've checked the nodes and cluster which are running, so I'm not sure what's causing this error.
