I have deployed quay.io/keycloak/keycloak:15.1.1 on an AWS ECS Cluster.The container logs are showing the following errors when running.

Database connection is working properly. However, I can only see errors related to Wildfly. The AWS ECS Cluster is running on private subnets, and internet traffic is routed through a load balancer.

(I have successfully run this image on Kubernetes with the same environment variables, but on ECS, it is not working.)

Can you guys help me to fix this problem?
