Error 404 after EUSSP login Afaria 7 SP03

Hello Community,

I have a problem after the login in the EUSSP of Afaria.

I can access the page normaly, but after I enter the login credentials, I got the error 404 Page not found. It worked fine but suddenly I get this error

I also have already installed the newest hotfix.

There is no firewall between, so nothing is blocked. I found also a KB article about that KB article 1855964, but I haven't installed the HTTP redirect feature.

Does anybody know how the error can be fixed?

Thanks and best regards

Michael
