Spring cloud app error in aws ecs environment

Question

The following is the problem description:

1. This error is only generated when the service is deployed on AWS ECS, there is no error in the local environment
2. Every microservice currently deployed will have this problem. This problem will not affect normal functions. The time of occurrence is also random.
3. The current spring cloud version is Dalston.SR4.

Here is the error log：
