Need help updating acme

I only asked for you to install acme.sh.
ONLY INSTALL
Is it installed?
Please show:
sudo /root/.acme.sh/acme.sh version

/root/.acme.sh/acme.sh version

v3.0.0

Perfect, now you have an ACMEv2 compatible client installed.
Now lets try to use it to get the cert you need...

We will replace this certbot plan with acme.sh

Try:

apachectl -k stop
/root/.acme.sh/acme.sh --issue --standalone -d your.mail.domain -m your.email.address
apachectl -k start

apachectl -k stop
httpd (no pid file) not running
/root/.acme.sh/acme.sh --issue --standalone -d mail.ivanovoobl.ru -m it@ivanovoobl.ru

Apache did not stop?
[it must first stop]
How do you stop Apache?

This is also a bit of a problem here:

it is not running as I mentioned earlier

I know what you said.
But something is still there:

curl -Iki http://mail.ivanovoobl.ru/
HTTP/1.1 503 Service Temporarily Unavailable
Date: Fri, 30 Jul 2021 21:50:27 GMT
Connection: close
Content-Type: text/html; charset=iso-8859-1

so what to do?

Follow the packets...
How does the Internet reach your server?
How do you know that Apache is not running?
Please show:
sudo ps -ef | grep -Ei 'apache|http' | grep -v grep
sudo netstat -pant | grep -E '80|443'

sudo ps -ef | grep -Ei 'apache|http' | grep -v grep
sudo netstat -pant | grep -E '80|443'

I also don't see any Apache running.
So, whatever is responding with "503" is likely part of the problem.

What does your server plug into?

I didn't quite understand your question

so what should I do?

You need to find the device that is responding to HTTP (with the 503 error).
Once found, you can begin to understand how to reconfigure it to your needs.

I did not set up this "kitchen" could you explain what exactly to look for and look for

Follow the wires.
What does your server plug into?
What does that plug into?
...
[how to do reach the Internet - how does it reach you?]

tell me what ip and what domain name to specify in the dns record so that my server can reach the letsencrypt resource because there is no connection between them then the command
Â

sudo certbot certonly --manual --manual-public-ip-logging-ok --preferred-challenges dns-01 --server https://acme-v02.api.letsencrypt.org/directory -d mail.ivanovoobl.ru -m it@ivanovoobl.ru

Â

What do you mean?
Please show any error or message.

according to this type, I need to add the ip and the name lensencrypt so that the command works and letsencrypt can reach my server
