CodeDeploy를 통해서 EC2에 앱을 배포할려고 합니다 배포를 실행해도 CodeDeploy agent was not able to receive the lifecycle event. Check the CodeDeploy agent logs on your host and make sure the agent is running and can connect to the CodeDeploy server. 라고 오류가 발생하며 실패합니다.

EC2 상에서 CodeDeploy Agent의 로그를 확인하면 위와 같이 로그가 계속 찍히는데 관련해서 해결책을 검색해서 시도를 해봤습니다.

1. IAM 역활 지정
2. EC2 역활 지정
3. IAM User 액세스 토큰 다시 발급
4. CodeDeploy 재설치

위 4가지 방법을 다시 확인해도 로그 상에서는 배포를 하지 않아도 Agent가 계속 Security Token에 대해 반복적으로 ERROR 로그가 발생합니다.
