My sites offline after renew certificates

any can help me?

I can’t bring my sites back online.
yesterday they were all online.

I installed everyone with this script:
sudo ee site create –type = wp –ssl = le –cache –yes

the path is / opt / easyengine / sites

I was having trouble with certificate renewal.
I was unable to renew, I tried to use certbot, easyengine commands, …
I could only renew after creating / etc / nginx / sites-availables blocks

but after I did that, they all went offline.

What did I do? I deleted my sites?
Shouldn’t I have made changes to nginx? since easyengine set it up all by itself?
