Hello

I added certificate to domain and everything works fine.
But i have problem with ftp.domain.com

There is no Letsencrypt information

Also i have a question: how to add ssl to direct admin :2222

I tried add SSL=1 in /usr/local/directadmin/conf/directadmin.conf
But then i can't restart directadmin:

[root@main ~]# systemctl restart directadmin
Job for directadmin.service failed because a configured resource limit was exceeded. See "systemctl status directadmin.service" and "journalctl -xe" for details.

When i switch SSL to 0, directadmin restarting

My current directadmin.conf:
