I am at my wits end with trying to get our connection broker's into HA, hoping someone has additional ideas as I've sunk an obscene amount of time into this already. Feels like the HA piece of the RDS Connection Broker got about 20min of development.
Problem: Server Manager (Tried via PowerShell also) HA wizard refuses to connect to SQL instance.

Clik here to view.
Configuration
- Server 2019 RDS/Connection Brokers
- SQL 2017 Failover Cluster, Named Instance
- Connection Brokers security group exists with both RDCB's as members. Group has dbcreator writes on the SQL server.
- Tried pre-creating the database and giving dbowner, no difference.
- I've tried with the download SQL Native client, 2012, the latest. I've tried using the Client Tools included with SQL 2017 media. I've tried with the Client Tools included with SQL 2016 SP1
- No windows firewalls
- Every other application/connection test is successful to the SQL cluster.
- Using a UDL file to test the connection string from the connection brokers to the cluster is successful.
- Tried "Dedicated database server" and "Shared Datababase server"
- I've tried connection strings using Trusted Connection and user authentication.
Absolutely nothing I do will allow the HA piece of RDS to recognize and connect to the SQL instance, it's absolutely poor code or a bug I just don't know how to get around it.
