Problems launching command "sudo service apache2 status" in web server

Question

I comment my situation:

I joined a new job (first job), the issue is that I need to certify the SSL certificates of some web pages via Certbot, I have tried everything (Both on the web server and locally through Apache) and I have had many problems to be able to perform certification.

First of all, on the server when trying to use the "sudo" command, it gives me the following error: internet:~# sudo service apache2 status sudo: service: command not found

And secondly, when performing the certification at the "local" level, it gives me the following error: root@-: # sudo certbot certonly --apache Saving debug log to /var/log/letsencrypt/letsencrypt.log Please enter the domain name(s) you would like on your certificate (comma and/or space separated) (Enter 'c' to cancel): webmail.pacifik.cl Requesting a certificate for webmail.-.cl

Certbot failed to authenticate some domains (authenticator: apache). The Certificate Authority reported these problems: Domain: -------- Type: unauthorized Detail: 190.121.-.- : Invalid response from http://webmail.-.cl/.well-known/acme-challenge/ -: 404

Hint: The Certificate Authority failed to verify the temporary Apache configuration changes made by Certbot. Ensure that the listed domains point to this Apache server and that it is accessible from the internet.

Some challenges have failed. Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.

Does anyone know how I can move forward?
