I have Debian 9 server with apache on digital ocean, and i was following a guide posted on digital ocean to setup ssl with let’s encrypt. I have one domain pointed to this server with 301 permanent redirection to www. done with mod_rewrite rule enabled. During the installation it asked me for which domain to setup https and i selected the second domain (the one with www).
But in the end of the setup process i get this message: “Client with the currently selected authenticator does not support any combination of challenges that will satisfy the CA.” And if i test my domain here: https://www.ssllabs.com/ssltest/analyze.html?d=example.com&latest it shows that it can’t connect to the server.
Why i am getting this error and what does it mean?
