Problem to renew the certificate

My domain is:

I ran this command: certbot-auto renew

It produced this output:

My web server is (include version): debian 8.10 jessie

My hosting provider, if applicable, is: hostwinds

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): No

Good afternoon.

I’m very new to this and that’s why I ask for help through the forum. I imagine that the problem that I will pose is more than reported; but I do not get along well with English and do what I can … apologize for it.

At the time I got the courage to create a certificate and install it on the server where I have a Wordpress deployed. Well, until there and except for a couple of questions, I managed to deploy the server certificate.

Today I have to renew the certificate, since it expires on June 8 and the system returns errors that I do not know where to fix them.

The wordpress installation path is: /var/www/html/wordpress
The letsencrypt path is: /etc/bin/letsencrypt

Please help!!

I created a hello.txt inside /var/www/html/wordpress/.well-know and this is visible from the browser.

I do not know where else to look.

:frowning: has an IP address:

$ host has address

But doesn’t.

You have to go to your DNS control panel and add an A record with that IP (probably).

Oh yeah!!

Fantastic!! That was the problem.

It has been adding the host “@” pointing to IP and the certificate has already been renewed.

Thank you very much for the help and for the speed.

Now what I have left is to program it in the Linux cron.
