After moving SCCM SQL DB to a cluster, SCCM couldn't connect to the DB

[FactorVIII]

Hi Everyone, I am migrating our SQL DB to a cluster and the last error in configmgrsetup.log is 

Site server does not have admin rights on remote sql server machine db_sccm.domain.com.

I made sure the main servers computer account had full permission on the servers hosting the cluster. Any idea what I'm missing?

The site server account must be both SA and administrator on all nodes within the cluster. You will also want to preform a site reset too, to ensure all the services and permissions are correct.

@ appreciate the response Garth, I saw you responded to my reddit thread I'll update there.
