Help somebody...

 

I launched Apache2 somehow. I just moved @100-abcmotors.lt.vhost from /sites-enabled.
Then i had fully deleted this site from server.
Thanks to God now my server (all other sites) working.
What it was? i tried this tutorial: https://tomlankhorst.nl/free-ssl-certificates-use-lets-encrypt-with-ispconfig/

 

ISPConfig 3 manage by default sites with LetsEncrypt. Of course, letsencrypt must be installed.

 

that tutorial is about ssl on ispconfig 3.

 

Yes, no doubt. But why all the trouble when ISPConfig can make all the modifications to vhosts, without manual intervention.

That article is very old. Then, ISPConfig - LetsEncrypt implementation was not added. Update to the latest ISPConfig version, and you will see on every website hosted two checkboxes SSL and Let's Encrypt SSL.

 

i use older, 3.0
and planning to upgrade to newest this summer, just i will need to move some important webs. Little scary.

 

Anyway... all the info about the error you can find it in /var/log/ispconfig/httpd/abcmotors.lt/error.log...
