Hi, unfortunately on my ISPconfig 3.1.1p1 (Debian 8.6) i cannot get SSL running. I started ~1,5 years ago with installing certbot from htt ps://dl. eff. org/certbot-auto (which was working, but just manually), later i installed letsencrypt via apt and i guess that was the point where things turned to a mess. At the moment, ssl connection are not working at all. i try to find the reason, my guess is that ispconfig uses other cert paths than letsencrypt (installed with apt). When i try to connect on the SSL site, i guess a "SSL_ERROR_RX_RECORD_TOO_LONG" error, but i think that's not the real reason because ssllabs.com/ssltest reports "Assessment failed: No secure protocols supported". Obviously tagging SSL and Letsencrypt SSL checkboxes in ispconfig does not have any impact at all at the moment, so my guess is that there is something brokwn in the apache configuration in general. Could anyone give me a hint where to look at first? Thank you very much for your help.
