Report Server with Forms Authentication always redirect to Logon.aspx

Hi everyone,


I have on premise installation of PowerBI 2020, used with Forms Authentication., with all setups decribed in the article.


Whenever I am trying to open Reports page, I am always redirected to Logon.aspx in an infinite loop. The forms cookie is there, whenever I hit the logon.aspx page the user is authenticated (I can debug it).


The ReportServer page, however, is shown without problems.


Does anyone know how it can be fixed?


Thank you.
