CORS Ec2 instance behind an ELB Load Balancer about django-cors-headers HOT 4 CLOSED

This should be unaffected by such environments, as long as you have a stable DNS pointing at your site, such as example.com. I'm using it on instances behind an ELB just fine.

That’s interesting you’re able to get this working. When my ELB environment spins up more then one EC2 instance all of my requests start failing with cors preflight errors. If only one instance is running I have no issues at all. If I disable cors or make requests through postman it works fine. Not sure what the problem is.

@adamchainz Have you seen this successfully working when you have more then one instance running behind an ELB?

Yes, I can't imagine how you're getting a problem with more than one instance. I think this is an AWS question not a problem with this library.
