Hi all, I'm trying to make work from a url like https://subdomain.mydomain.com a docker image without much success. Under the Apache options I got the following: Code: ProxyPreserveHost On ProxyPass /.well-known/acme/ ! ProxyPass / http://my-public-ip:9000/ ProxyPassReverse / http://my-public-ip:9000/ Header always set Access-Control-Allow-Origin "https://subdomain.mydomain.com" Header always set Access-Control-Max-Age "1000" Header always set Access-Control-Allow-Headers "X-Requested-With, Content-Type, Origin, Authorization, Accept, Client-Security-Token, Accept-Encoding" Header always set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT" RewriteEngine On RewriteCond %{REQUEST_METHOD} OPTIONS RewriteRule ^(.*)$ $1 [R=200,L] SSLUseStapling off If I call the url subdomain.mydomain.com without https and with the port 9000 it works fine. Without the port it just shows the default ispconfig page. With https and 9000 port at the end it doesn't work at all, it throws Error code: SSL_ERROR_RX_RECORD_TOO_LONG Any help is very much appreciated.
