AWS ElasticBeanstalk + Socket.IO + SSL issue

I'm having trouble working with AWS ElasticBeanstalk with NodeJS environment + Socket.IO + SSL for our messaging app.

I'm already running in circles trying to fix the issue but I always ends up to a Websocket handshake error (504 GATEWAY_TIMEOUT).

AWS Elastic Beanstalk Load Balancer configuration:

Thanks in advance. Any help is highly appreciated!

Finally!!! Got it!

So after a lot of hours burned, this solution works for me.

The problem is that I have HTTPS in my load balancer pointed to HTTP on my ec2 instance. That causes a problem because websocket runs on TCP and not HTTP/S. The port number also did matter in my case.

Original config (not-working)

I hope this can be of any help in the future. :-)
