Direct query to Dataflow returns Proxy Authentication error

[gmckinnon]

Hi, I have a dataflow in premium capacity with enhanced compute engine turned on. When I try and direct query to it in power bi desktop I am getting this error;

"

An error occurred while sending the request.;The remote server returned an error: (407) Proxy Authentication Required.. The exception was raised by the IDbCommand interface.

"

This seemed to be working last week so unsure what has changed. I can import the data into desktop, only direct query is not working now
