Theming of the login page is not working

[Fly87]

Hi Team,

i just looked to this page, to theme the login page:
https://documentation.open-xchange.c...ogin-page.html

I tried to change the default theme in the folder:
/opt/open-xchange/appsuite/apps/themes/login

and changed the login.less file but nothing happens.
I tried to execute the update-themes.sh script and it worked successfully but the theme has not changed.

The next step i tried is to create a new, own login theme as described.
Ich changed the as-config.yml with my theme but nothing happens.

I have only the default style. And i restartet the ox server, the whole server.

Could you help me to understand this issue.

Thanks

Regards
