Hi @losesten,
What is the domain that you are attempting to issue a certificate for? Does your Windows 10 server have ports 80/tcp and 443/tcp open?
There are several others who run WAMP and use Let’s Encrypt certificates. From a quick forum search I found the following threads:
- WAMP and Let's Encrypt
- Setting up SSL on Xampp
- This might help https://www.docketrun.com/blog/how-to-setup-lets-encrypt-for-apache-on-xamp-wamp-in-windows-vm/ Edit: This one may be outdated
