DataSource.Error: OData: Request failed: The underlying connection was closed: Could not establish

[powerbiuser1231]

I'm getting this error when trying to set up a dataflow to connect to an API.

"DataSource.Error: OData: Request failed: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."

I've tested trying to call the API from Power BI Desktop and that works fine. Not sure why this is not working when trying to use it in a dataflow.

Hi @powerbiuser1231 

If you have it working through Desktop, you can create a Dataflow from Blank Query and copy/paste your M code from the Advanced Editor in Desktop.
