Lets Encrypt in 3.1b2

Hi guys,
I want to test Lets encrypt in ISP COnfig v 3.1b2 but it seem, that doesn work. Maybe I do something wrong, but maybe it is caused by missing manual. I have new fresh install Debian 8 with new fresh installation ISP Conf 3.1b2 and try to use https on test website. I create test webpage (FQDN, create DNS record, which working fine) and in setting of this webpage I check "Lets encrypt SSL". But nothing happend. HTTPS doesnt work, no error in log. If I check again setting fot this test webpage there is not check "SSL" and "Lets Encrypt SSL". Do you have any idea what I do wrong or what can I check?
Thank you

Edit: Installation was done step by step under this manual https://www.howtoforge.com/tutorial...-8-4-jessie-apache-bind-dovecot-ispconfig-3-1

 

"test website". letsencrypt's use public DNS to check if u own the site.
every one in the world can see your http://"test website"/.well-known/acme-challenge/ ?

 

Have you installed letsencrypt?

Code:

cd ~
wget https://dl.eff.org/certbot-auto
chmod a+x certbot-auto
./certbot-auto

 

After installation by Thaddeus manual it work well.
It is strange, because I dont expect, that I must do something else than is in manual. So I think, that will be good add this step to installation manual. Thank you guys a lot.

 

@till please add this to isp install :-D

 

Thank you guys.

===============================

so i did it the manual way , the interface is creating only self signed so i stopped apache2 , did standalone CLI , renamed key and cert in www.domain.tld.key and crt copied in /var/www/domain.tld/ssl/
the script is not working ...don`t know why can`t contact the site ..maybe it needed a directive or rights to inject the challenge in the webroot. i`ll search more but i can confirm : it`s not working from the interface .
