[Django]-Django Elastic Beanstalk App – Cannot Set Secure Listener Port to 443: LoadBalancerHTTPSPort

I had the same problem with a NodeJS Elastic Beanstalk app. However, I was able to get around it by updating the Listener/Certificate settings via the AWS EC2 console (https://console.aws.amazon.com/ec2/), via the Load Balancers section (under LOAD BALANCING).

I was updating the certificate for a staging version of a cloned environment. This was the only way I could assign a different certificate to the staging environment.
