problem with admin configuration for Webscreens

i have installed webscreens on Sage 300 2022.1 and able to login with webscreens and desktop without issues.  However, i am in need of loading some customized UI's from a 3rd party developer but can't login in to the admin configuration   (http://servername/sage300/admin).  it just shows that there is a problem occuring when signing into the web screens.  Try siging in to the Sage 300 desktop and activate data for all company databaes that use the same system database before signing in to webscreens.

There is just one company database and i was successful logging into webscreens (http://servername/sage300), rebooted the computer as well as updated the web.config file so that the AllowWebApiAccessForAdmin to be true.

What else should I be looking at to get this configured?  or is there another way of uploading customized UI for webscreens?
