I really like this free-way to obtain a free SSL/TLS certificate. But I can not make it work.
I wanted to try how Let’s Encrypt works. I created a virtual machine with Debian. I installed Apache2 and configured the HTTPS. But when I want to get the certificate, it tells me that I need a DNS server with a A record.
Here is mi question, there is any way to obtain a LE certificate in a virtual machine without a DNS record. I just want to work with a Test Enviroment. I do not want to have a real Apache2 working on the Internet.
Thank you very much and sorry for any issue, I am a beginner in this. But I want to learn.
