Question: Hi I would like to know how I can make my page scroll when arrow keys are pressed. Like this page: <http://spacexstats.xyz>. Java script and jQuery are accepted.

Thanks, Ivan.

Answer: 
You should setup HTTPS connection on the LB, then you'll have a proper TLS connection between the LB and the tomcat so spring will stop crying. You'll just have to provide a self-signed certificate to the LB and setup your spring security module with the private key that have generated this self signed certificate.

(a more complex option: setup properly the tomcat proxy, to force it to encapsulate the HTTP stream of the LB in an HTTPS stream. Setup all TLS requirements in the proxy: certificate, private key...)
Did you try to put LB address as proxyName? It might work on your case.
