Fiori launchpad basic authentication popup

Hello

I have configured the login class /UI2/CL_SRA_LOGIN for the ushell node but i am still getting this pop up

I checked and the same identical configuration (pre-delivered) is for /default_host/sap/bc/ui5_ui5/ui2/launchpage and also for /default_host/sap/bc/ui5_ui5/sap/ar_srvc_launch and there the login page looks like this

How do i correct the issue with the fiori launchpad log on page to be the same as above?
