Hello, I used the Okta documentation at Add user authentication to your Node.js Express app | Okta Developer to set up Okta on an Express js app. It runs fine on a container on localhost.
When I deploy it to ECS behind an application load balancer, attempting to hit the Okta protected route times out, I can see that the application is authenticating against the Okta tenant, and a callback code is being passed back to the application, but I am unable to access the Okta protected route, and the ALB is throwing a 504.
