ERR_SSL_PROTOCOL_ERROR with ISPConfig 3.1Beta2
I installed a Debian Jessie server as instructed here: https://www.howtoforge.com/tutorial/perfect-server-debian-8-4-jessie-apache-bind-dovecot-ispconfig-3-1/
When I make a website the let's encrypt function does not work. Before you ask:
- yes I'm shure DNS points towards my server I checked with whatsmydns.net before making it.
- yes I followed each step as instructed.
- yes I tested more than once.
Setting up the site works fine and I can access it through HTTP but not through HTTPS. There I get this error: ERR_SSL_PROTOCOL_ERROR
