GET requests with Web connector

I need to load csv files from AWS S3.


Unlike this question, I am using a signed url to access the data. The url works in fine in the webbrowser, but in Power BI desktop Web connector it throws the following exception: 


DataSource.Error: Web.Contents failed to get contents from 'https://s3.<signed url>' (400): Bad Request
    DataSourcePath=https://s3.<signed url>

Does anyone know what the reason for that is?

Hi @orange_yoshi,


Please try to type the same URL in IE browser inprivate mode to see if it works fine firstly. 


When you use web data source in Power BI desktop, does it provide you to enter any credential?

Hi @v-qiuyu-msft, and thanks!


I tested the link in IE and Edge, both in normal and private mode, everytime without any problems.


PowerBI desktop does not prompt for any credentials. Authentication is done via digital signature in the url.
