Custom Authentication in Power BI Report Server

Hello,

we applied this authentication method to our system and it is working fine. We have 6 Report Server as ScaleOuted. But some of our Business Teams wants to be login portal with Windows Authentication.  Then we changed on of the servers authentication methods to Windows NTLM. But when we want to login to portal system give us "Could Not Load the Folder Content. Something went wrong Please Try later."

I tried lots of things,

* I removed server from scaled out ( did not run)

* I added new portal url in ReportServerUrl string in reportserver.config

does anyone have any idea what is wrong?

in RSportal log we found below log
