Não consigo renovar o certificado

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: test.megatest.com.br

I ran this command: certbot -q renew

It produced this output:

Attempting to renew cert (test.megatest.com.br) from /etc/letsencrypt/renewal/test.megatest.com.br.conf produced an unexpected error: Problem binding to port 80: Could not bind to IPv4 or IPv6… Skipping.
All renewal attempts failed. The following certs could not be renewed:
/etc/letsencrypt/live/test.megatest.com.br/fullchain.pem (failure)

My web server is (include version): apache2

The operating system my web server runs on is (include version): Debian 4.9.168-1+deb9u5

My hosting provider, if applicable, is: registro.br

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):

Can you post the rest of Certbot’s output, and the contents of /etc/letsencrypt/renewal/test.megatest.com.br.conf?

This would require you to shutdown the apache server first.

As shown by error message:

6 timers listed.
Pass --all to see loaded but inactive timers, too.

There should be more output to the right.
Otherwise try:
systemctl list-timers | grep cert

The output should be like this:

OK so there is already a certbot job to renew.

Please show files:

Description=Run certbot twice daily

OnCalendar=--* 00,12:00:00



ExecStart=/usr/bin/certbot -q renew

Ok, you do have a job that tries to renew.

But now we have to make this:

do these 3 steps:

For that we can use hooks.
First we try to create a working single statement and then we update the timer job.

So, lets try it (in testing system) this way:
with this command string:

/usr/bin/certbot -q renew --pre-hook "systemctl stop apache2" --post-hook "systemctl start apache2" --dry-run
