Posted in ActionCable Production Error - Websocket Handshake 404

Hello all,

I've been trying to figure out this actioncable Websocket error I'm getting on production in an AWS EB environment on an Application Load Balancer. It's a 404 error and also Failed to Upgrade Websocket in the logs. I've tried possibly the first 5 pages of google and even Bing results looking for answers. I've also configured the nginx.conf file in many different ways in suggestions. Seems like no one wants to attempt to help on StackOverflow. I've followed Chris's videos and tried it the exact way.

Here's a link to my SO post for more information:

I appreciate the help and you reading this.
