thanks for your comment but i still don't see anything on my google cloud console after the refresh fails.
The only issue is the PowerBi Service (Cloud) but sometime it works on weekends. On PowerBi desktop i've never had an issue refreshing the data. This is why i assume the issue resides in the Powerbi connector and has nothing to do with Google BigQuery. The only thing that comes in my mind is google detecting that a lot of requests are being made from the same ip/machine that makes several calls at the same time, but uses diferent credentials.
It shoudn't be an easy task otherwise powerbi team already have sorted that out. This thread it's been around for some time already.
giusvizz the last time i've got an answer from microsoft, was told me that they are thinging on a solution for this but there's no ETA for this. Besides that i don't have another info. Which i would...
