Just installed the latest Beta version 3.1 - upgraded from older install. According to the feature request thread, Let's Encrypt is integrated in 3.1, but I am not sure how it works or what procedures are required? I presumed I had to install Let's Encrypt, which I did, however there were a few screens I was not expecting about selecting which domains to enable SSL and I got errors on install with a "Failed authorization procedure" as the process seemed to be looking for the reverse dns of the server ":: The server could not connect to the client to verify the domain :: DNS problem: NXDOMAIN looking up A." I then checked both the the SSL and Let's Encrypt boxes for the domain in the ISPConfig 3.1 control panel. Went to SSL tab and filled in info and country, then selected to create certificate, then returned to save certificate. However certificate is just a self signed untrusted certificate with broken https and .err document. Any walk through for installation and pointers on how to use Let's Encrypt please?
