Letsencrypt not working

NethServer release 7.6.1810 (final)
3.10.0-957.27.2.el7.x86_64

Letsencrypt authentication expired yesterday. Unable to renew.
Nothing changed.
I’ve already seen everything and don’t understand what?

Can you post the contents of the most recent file in /var/log/letsencrypt?

Here’s your problem–your server is responding with a 403 error when the Let’s Encrypt servers try to check the validation token. It’s unclear why it would be doing this, though–have you installed any web applications on the system?

I didn’t install it.
Web application only for nextcloud.
No changes in the last 3 months, only updates.

Does the acme-challenge directory exist?

[root@server2 ~]# ls -l /var/www/html/.well-known/
total 0
drwxr-xr-x 2 root root 6 Jul 28 20:55 acme-challenge

[root@server ~]# ls -l /var/www/html/.well-known/

total 4

drwxr-xr-x 2 root root 4096 Sep 10 19:41 acme-challenge

Let’s check if there is a vhost error:

httpd -S

I’m wondering if there’s a .htaccess file in /var/www/html.
