502 proxy Error [error reading from remote server]

Question

I get an error with my https site. when I work with my http site, it works great on APACHE2 on Ubuntu 14.04.

here is my virtual host configuration for https site

<VirtualHost _default_:443>



                         SSLProxyEngine On
                         ProxyRequests Off
                         ProxyPreserveHost On
                         RequestHeader set Front-End-Https "On"

                        servername jenkins.mydomain.com
          Proxypass / https://192.168.0.93:8080/  Keepalive=on
                        ProxypassReverse / https://jenkins.mydomain.com/


                        SSLEngine on
                        SSLCertificateFile      /etc/apache2/ssl/wildcard.crt

                        ErrorLog ${APACHE_LOG_DIR}/error.log
                        CustomLog ${APACHE_LOG_DIR}/access.log combined
