Power BI Embedded: OpenConnectionError

Hello all,

I'm working on embedding reports for a client and am running into an error that isn't really getting many google results. This is the only post showing the same error that I've found. I've triple checked my stuff and haven't found any rogue extra spaces anywhere.

Any ideas on how to troubleshoot this further?

Client is set up using Service Principal and RLS.

Error:

Underlying Error: PowerBI service client received error HTTP response. HttpStatus: 503. PowerBIErrorCode: OpenConnectionError
OpenConnectionError: Failed to open the MSOLAP connection.
