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. crt.sh | maison.francois.cc), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: maison.francois.cc
I ran this command: Create new cert from synology interface

My web server is (include version):
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is: Free; fixed IP
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): Synology 7.0.1
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):
Your IPv4 and your IPv6 point to different machines (or your server is listening differently on them.) (No, not really, nmap isn't telling that, but you should still check it. Ok, I'm changing my mind again, nmap tells me that, if I scan the standard ports instead of port 80 alone.)
IPv4 needs port forwarding but each device on your network has their own public IPv6 address. You need to use the right one, the IPv4 for the router but the IPv6 for the actual device.
