Hello,
Thank you for posting in Q&A forum.
Based on the error information you provided and according to Microsoft documentation, to solve this problem, please use one of the following methods:
- Set up RDS without Connection Broker for a single-server installation.
- Don't disable TLS 1.0 on a single Connection Broker deployment.
- Configure a high availability Connection Broker deployment that uses dedicated SQL Server.
- Upgrade the computers that run the RDS services to Windows Server 2019.
I hope the information above is helpful.
Best regards
Zunhui
