Issue/Introduction

 

When trying to reverse proxy to Wildfly 8.2 Jboss on https port from CA Access Gateway (SPS). Though both Apache on CA Access Gateway (SPS) and Jboss are listening on https ports, but when the reverse proxy rule is configured to forward request to Jboss on https port it fails with a noodle error.

   The back-end Server(<servername>) Certificate presented is bad
