.well-known folder is not being created

Upon executing the command below certbot says that the connection timed out, but it should be able to connect just fine, as I manually created the folders afterwards. If I delete them, certbot doesn’t create any folders/files, so I think it could be a permission issue of sorts, but I couldn’t find any help online.

My domain is: cnmb10a.ddns.net

I ran this command: sudo certbot certonly --webroot -w /var/www/html/ -d cnmb10a.ddns.net

It produced this output: Saving debug log to /var/log/letsencrypt/letsencrypt.log

    To fix these errors, please make sure that your domain name was
    entered correctly and the DNS A/AAAA 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.

Your site isn’t reachable from the world wide web in general. Not from my location and not from https://downforeveryoneorjustme.com/cnmb10a.ddns.net

Is the currently resolving IP address for that hostname even correct?

Thank you for your reply, the address is correct, it’s just that I haven’t thought of testing it from outside the local network, where it works just fine. I will look for the issue there and update if it’s still not working.
