My domain is:alebalweb.com

I ran this command: sudo certbot renew --dry-run

It produced this output:
Domain: www.alebalweb.com
Type: unauthorized
Detail: 185.217.95.56: Invalid response from https://www.alebalweb.com/.well-known/acme-challenge/PPY0h0Z8qeUjU4SbozmIyLCyCEIsamZmadbLniCi_PA: 404

My web server is (include version): apache2

The operating system my web server runs on is (include version):ubuntu 20.04

My hosting provider, if applicable, is:vicetemple, namesilo

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

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):certbot 1.27.0

Hi my server in on vicetemple, i use namesilo dns i create my certbot certificates in this server without problems, but now i can't modify my certbot in any way.

Looks like i miss something... I saw there are a lot of similar questions, i read them, but i don't understand what they do to solve, someone seems to have modified virtual host, some maybe add ipv6, some an AAAA dns record... I don't know what to do...

This is my dns configuration on namesilo

My server often says: sudo: unable to resolve host vicetemple-ubuntu-20-04: Name or service not known could this be a problem?

I don't think that is the actual "problem" that is preventing the certificate issuance.
But you could try adding an entry in the /etc/hosts file to get past it.

That said, are there any other errors in the LE log file?

And in any case, have you tried using --webroot authentication?

That'all the error i found...

What's ---webroot?

OP is showing the log from the cerbot certificates run :wink:

What???

When @rg305 asked for other errors in the LE log file, he meant the log file of the renewal attempt. The log file you're showing now is from the certbot certificates command and would not contain an error of the renewal attempt.

That's another way of authenticating.

The error is always the same...

Maybe solved... for now...

server admin (vicetemple) had to do something, they say they do this:

We mannaly created
/.well-known/acme-challenge/0UMHOsrL0Grn-34UtBcF8PlpqT0W4BrUSDON3p5MTXs

now work... but i have no idea what happened... and i would like to understand...

It's a terrible idea to add (and remove) the challenge file manually, as this can't be automated.

If you can't find the appropriate log file manually, please follow the following steps:

  • Run sudo certbot renew --dry-run again; it will most likely fail again;
  • Don't run certbot after that command again for now;
  • Show the contents of the file /var/log/letsencrypt/letsencrypt.log here.

Two problems:

  • can't spell "manually"
  • doing anything "manually" in 2022 is likely unnecessary
