So I have an application that I am deploying through a docker container in ECS service. And I am using Amazon Cognito through application load balancer for authenticating into the application.

When I configured this with internet-facing Application Load Balancer(ALB), everything worked fine. But now when I changed my ALB to internal, it is throwing an error 500 Internal Server Error.

Has anyone seen similar scenario?

The way I solved this problem was by adding a rule on Load balancer listener - On Unauthenticated - allow
