AWS Load Balancer Configuration

Looking for guidance on the appropriate AWS settings for a bokeh server configuration using Amazon certificate on classic load balancer (Elastic Beanstalk).

I have most of this working but the webservice callback is errorring out (400) as follows:

bokeh.min.js?v=ac90935137e13ae0b2c6583f2e1f3fe8:608 WebSocket connection to 'ws://' failed: Error during WebSocket handshake: Unexpected response code: 400

This appears to be an issue with the associated protocol being blocked by the VPC/security group setup on AWS. If there are some sample shots of how this should be configured it would be much appreciated as I have been beating this up for a while now.
