Currently I am experiencing "Connection to Server Failed. Error 400 error." only when I access the desktop site. The mobile site runs normally.

The topology is as follows: User -> Reverse Proxy (NGINX) -> ADSelfService Plus Server.

I have installed the certificate on ADSelfService Plus and I set it to access using https port 443.

What configuration do I need to ensure in ADSelfService Plus that might cause error 400 as in the picture?
