I am using a Synology NAS version DSM 5.2-5967 Update 9. Unfortunately, it is impossible for me to install
certbot on it. So I’m trying to get my certificate from another computer. But I have a problem with the “http challenge”. I have access to the files in the “http://maison.ilp-web.net/.well-known/acme-challenge/” folder, but I can’t figure out which file to create and with what content before the challenge is completed. And this one changes with each of my attempts. Anyone have a solution so I can create the file before?
My domain is: maison.ilp-web.net
I ran this command:
sudo certbot certonly --standalone -d maison.ilp-web.net --preferred-challenges http
It produced this output:
Some challenges have failed.
The following errors were reported by the server:

certbot --version or
certbot-auto --version if you’re using Certbot):
