Nodejs Socket with HTTPS not working on AWS Instance/Load Balancer

I have Node Js Socket IO (using express) , version 4.2.0 - working fine with http connection on AWS, but with https from Client(Android) it gets xhr pool error and at times it seems that it reach to AWS Node JS instance (https certification is already setup for it)but keeps disconnecting. I am looking for someone who is expert both to look from NodeJs side as well on AWS if HTTPS/Load balancing is setup correctly for NODE JS SOCKET .
