Hi, When I attempt to connect to roundcube with https I get "secure connection failure" happens on Firefox and Chrome. If I use http://mydomain.net:8081/squirrelmail, I can reach the login box but it tells me it is not secure. I've double checked my nginx entries for the domain, they are right out of the "The Perfect Server - CentOS 7 x86_64 (nginx, Dovecot, ISPConfig 3)" from 2014 (it's been a while) I have 'letsencrypt' turned on for the website and all the websites on this server. I can get to the host with https or http with no problem. Ispconfig come up with https. I've checked out the certs at SSL Protocol Test https://www.ssllabs.com/ssltest/ The log for the domain has a handshake error: 2017/10/20 10:43:49 [crit] 29165#0: *1054 SSL_do_handshake() failed (SSL: error:14094085:SSL routines:ssl3_read_bytes:ccs received early) while SSL handshaking, client: 220.127.116.11, server: 0.0.0.0:443 Can I get some insight as to how to fix this problem. My system consists of Centos7, nginx, dovecot, and Isp3config 3.1.7p1 Any help will be appreciated.
