HTTPS redirection of webapps not working anymore

On all of our machines the webapps running (for instance domain.com should be redirected to https:/webX.hostname.tld/roundcube on the hostnames are not forced to SSL anymore an remains unsecure on http:/webX.hostname.tld/roundcube.

Has something changed in the logic of DirectAdmin?

In options.conf we have:
redirect_host=webX.hostname.tld
redirect_host_https=yes
use_hostname_for_alias=yes

In directadmin.conf we have:
force_hostname=webX.hostname.tld
ssl_redirect_host=webX.hostname.tld

Also checked if there where some custom configs causing this issue. But also checked and found that is not the issue.

Also in /etc/httpd/conf/extra/httpd-alias.conf i see the https links are correctly specified.

We use nginx_apache by the way, any thougths?

same here with nginx_apache.

Versions?
And OS?

Apache to 2.4.26 upated for example.
DA Version Custombuild version and so on?
HTTP2?

And with wich version(s) did it worked before?

Same here, we just installed a new server with nginx_apache and the same happens.
