after Auto-Login, disappeared menu

[GjemajlK]

I set up an auto-login API with CURL, Login works, then show only "Websites & Domains".
Top Menu for Mail, Applications, Files ... missing.
Does anyone know why?

Redirect to https://1001.xydomain.tld.net:8443/enterprise/rsession_init.php?PHPSESSID=xxxxxx
works, but Menu missing.

Thanks and sorry my bad english.
