Where to set up Let's Encrypt

My domain name is hosted at my webhosting company.
For one sub domain in the DNS I changed the A address to my own IP address at home.
On that IP address I want to set up a website on my server in house using Let’s Encrypt.

Where do I need to request for the Let’s Encrypt certificate?
I tried it on my in house server, but that failed:

Please enter your domain name(s) (space-separated): my.domain.net
Attempting to obtain certificates... error running certbot:

Saving debug log to /var/snap/nextcloud/current/certs/certbot/logs/letsencrypt.log
Plugins selected: Authenticator webroot, Installer None

http-01 challenge for my.domain.net
Using the webroot path /var/snap/nextcloud/current/certs/certbot for all unmatched domains.

Cleaning up challenges
Some challenges have failed.
 - The following errors were reported by the server:

   Domain: my.domain.net
   Type:   connection
   Detail: Fetching
   Error getting validation data

   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.

So I think I have set up Let’s Encrypt at my webhosting company. Is that correct?

Kind regards,

Hi @guidovanharten

please share your domain name.


In the meantime...

This seems to indicate that your ACME client may be unable to find an exact match, within the configuration files, for to the domain name of the requested cert.
