Hi @lewmur,
Maybe I misunderstood your request, are you looking to for a publicly facing "xampp" site from your locally hosted machine?
I can see Server: Apache/2.4.56 (Win64) OpenSSL/1.1.1t PHP/8.2.4
$ curl -Ii http://lewmur.com
HTTP/1.1 200 OK

If my second assumption is correct please see
- Getting Started - Let's Encrypt
- ACME Client Implementations - Let's Encrypt since you will need an ACME Client to be issued certificates from Let’s Encrypt.
Edit
Also only Port 80 is accessible, which is enough to be issued a certificate using the HTTP-01 challenge. However typically for a webserver that is offering publicly facing service Port 443 (i.e. HTTPS) is also needed. I don't know "xampp" maybe it uses a different port.
