3.1b1: Let's Encrypt
I've enabled SSL and Let's Encypt for a domain - but it doesn't seem to do anything. When accessing the domain I get a "ERR_SSL_PROTOCOL_ERROR" in the browser.
I've installed according to the Ubuntu 16.04 howto on howtoforge (inncluding let's encrypt in /opt/). On the SSL Tab there seem to be only options for creating a self signed cert - but nothing about let's encrypt ... what am I missing?
