Portaladmin not accessible after installation

[conde]

Hello,

I did a fresh ArcGIS Portal 10.9.1 installation (on my laptop and on a server).

Site creation is successfully completed and I can login to arcgis/home with portal admin user.
But I am not able to log in portaladmin.

When I go to "https://portal.host.machine:7443/arcgis/portaladmin/" I see below screen.

I have tried on different browser (Edge, Firefox, Chrome, IE), same result.

I have no error in the portal logs.

Do you have any idea to solve the problem?

Thanks

I have the same problem:

Fresh install of portal 10.9.1.

Can access /portaladmin through webadapter AND though :7443/arcgis/portaladmin

Can login, but just gets redirected back to start where login links are!

Can request token, and can access that to access admin pages, but this is to cumbersome.

I guess they broke something implementing the oauth thingy to replace the old form login for the admin page.

I tried with a different admin user. Same problem
