Welcome to the Let's Encrypt Community, Dr Cold :slightly_smiling_face:

Let's see here... :thinking:

You're trying to use manual authentication, which means you would need to create the authentication file by hand or with a script (or hook).

Could you try this for me, please:
sudo certbot run --cert-name --apache -d ","

This may not work due to your Apache being in XAMPP, in which case I have another plan...

First, cleanup:
sudo certbot rollback

Then try this in alternative:
sudo certbot certonly --cert-name --webroot -w /opt/lampp/htdocs -d "," --deploy-hook "sudo /opt/lampp/lampp reloadapache"

You'll need to modify your Apache configuration a bit at this point to serve the correct certificate.

You were spot on correct. The first command came back with:
The requested apache plugin does not appear to be installed

The second command worked perfectly:

  • Congratulations! Your certificate and chain have been saved at: ...

Specifying the webroot was something I hadn't tried before. Thank you very much.


Fantastic! :smiley:

Now you need to serve your certificate...

I believe that the file you want to edit is:

You can hopefully edit it using:
sudo nano /opt/lampp/apache/conf/extra/httpd-ssl.conf

For now though, to not work blind, please run the following two commands and paste the results in a post with three backticks (```) on separate lines above and below each output:

sudo httpd -S

sudo cat /opt/lampp/apache/conf/extra/httpd-ssl.conf
