Yes, when this error occurs, the most likely reason is that a proxy authentication server on your network is blocking the web requests issued by Power BI Desktop.

 

If you want to analysis the trace log, pleae go to File > Options and settings > Options and then select Diagnostics from the options in the left pane. 

 

Here is the update log, you can find the update content of each power bi version. If you want to download the old version, please go to this link.

v-yuta-msft ,

 

Thanks for your answer. 

 

Yes we are behind the proxy but that is not the point. The point is that the July release seems not able to handle authentification behind a proxy. Previous releases (June release included) are just working fine with the proxy. On my point of view it is a bug of the July release. Going back to a previous release is a short term solution but I want to be sure that this issue will be corrected in the next PBI Desktop releases.

    You are not alone.  I'm seeing the same issue - earlier versions of Power BI authenticated without an issue; the current update claims that proxy authentication is preventing the login.  Our proxy has always required authentication and Power BI has never prompted me for credentials, so I assume it's been piggy-backing on Internet Explorer's sessions or something similar.
