To fix these errors, please make sure that your domain name was
entered correctly and the DNS A record(s) for that domain
contain(s) the right IP address. Additionally, please check that
your computer has a publicly routable IP address and that no
firewalls are preventing the server from communicating with the
client. If you’re using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided.
Hi @simon.malpel, if you’re using the TLS-SNI-01 verification method (which is possible with apache or standalone Certbot modes), the certificate authority needs to be able to connect to port 443 of your server. This could be prevented by a firewall, for example.
If you want to use port 80 for verification, there are options to do that; they just may not be the default for the method you are using.
Could you tell us what command you ran and how you are expecting the verification to take place?
