                          Windows 2022, SQL Server 2022, FCI cluster with 2 physical nodes. 5 instances of SQL Server running on the FCI cluster. I need to have TLS certification running on all 5 instances of SQL Server. Can a single TLS certificate (installed on the servers) be used for all 5 instances, or does it require a single certificate for each instance?
