Hello, I would appreciate getting assistance with getting my SSL cert working on ISPconfig 3.1. I spun up a new VPS server, Ubuntu 16 LTS, then used your Perfect Server guide: https://www.howtoforge.com/tutorial/perfect-server-ubuntu-16-04-nginx-bind-dovecot-and-ispconfig-3/ Then I upgraded MariaDB to version 10.1. Seems all is working fine. I can open the ISPconfig login page with httpS://u16.domain.com:8080 and get the usual Certificate Error (untrusted ssl cert), but can proceed to login to ISPconfig. Created a new website in preparation to install WordPress. I'll want to run the entire site via HTTPS. I enabled both checkboxes "SSL" and "Let's Encrypt SSL" for a new website. Next, I entered the info in the SSL tab. Created the SSL Cert with the "Create" SSL Action. The SSL tab does have the SSL Key, SSL Request, and SSL Certificate text. I have also checked the "Rewrite HTTP to HTTPS" box under the Redirect tab. I can access the new website's index.html page using HTTP. But with the https:// prefix on Chrome I get the error: ERR_CONNECTION_REFUSED. Firefox says "Unable to connect - Firefox can’t establish a connection to the server at app.domain.ca" I only have one IP address on this VPS server. I believe one IP for multiple hosted domains shouldn't be an issue based on other posts I read here? This will be an ecommerce site so I need the SSL working, especially to quality for credit card payments. I have not yet installed WordPress as I want to have SSL working first. I would appreciate your help. Thank you.
