config: nestjs, docker, redis(local)

when i run ‘npm run start:dev’, pop ‘connected redis’.
However, when I build a Docker file and launch a container, once Redis is connected, an error occurs.

connected redis

i already check REDIS_HOST, REDIS_PORT.
The key is that once the connection is successful, an error occurs.

Does anyone know?

pop ‘connected redis’ and dont show ECONNREFUSED error….
