Apache HTTPS to Tomcat http connectivity not working - apache

Question

I have 2 linux instances on AWS , a webserver that has apache running on it and the other has tomcat running it.
The website on apache is configured to process requests over https and internally the requests go to tomcat over http.
Things i have done so far w.r.t to ssl,
1) created self signed certificate on the apache server.
2) installed and enabled mod_ssl modules in my httpd.conf file
3) mapped my domain to required document root and also to required proxy pass settings in virtual hosts
the website is accessible over https but as soon as you click a link that makes a backend call to tomcat , it fails. I have looked through the net and have played around with all possible config changes not sure what is the issue.
My VirtualHost settings....
