SSMS (400) Bad Request error attempting connect to premium capacity dataset

I was uncertain whether to post this in the Service section or in the Developer section, sorry.

Please my primary post in the Service section, with pictures here

I'm trying to connect to data in a Premium Capacity workspace from SQL Server Management Studion v18.4

I get the workspace connection from Workspace Settings
choose login with Azure Active Directory - Universal with MFA (I get prompted for my corporate federated login, which succeeds)
am returned a (400) Bad Request error.

Any ideas or cause or remediation?
