Hope this is the right place to ask this question.
We have an existing website and are evaluating moving to Let’s encrypt for our certificates. As the site is quite used and we have a complex architecture (web servers mount a readonly webroot, it can only be modified fom a backend webserver with no access to internet, reverse proxies, no internet access from webservers etc) is it possible to do manually step by step the certificate request and the verification process?
I’ll try to explain better, is it possible to make the client ask me to do the required DNS modifications / put the eventual resources on our webroot?
I followed the various documnets on the website but couldn’t find info on this.
Thanks in advance!
