Configuring End-to-End Encryption

I've been having issues setting up End-to-End Encryption using the provided guidance:
https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/configuring-https-endtoend.html

I have a ASP.NET Core 2.2 Web application, and I need End-to-End configured to meet requirements regarding PHI. Right now, I have HTTPS enabled, but I can wireshark on an EC2 instance and see unencrypted traffic.

When I go through the guidance, all requests to my site end up failing. Is there something obvious I'm missing?

I've attempted using a Classic Load Balancer and an Application Load Balancer.
