Nestjs microservices with docker compose not working

Question

When I run nestjs with docker compose, the microservices redirects don't work, but in the "nest start" command, the application plays as I want.

gateway api response

connect ECONNREFUSED 127.0.0.1:3000
gateway    |     at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1494:16) {
gateway    |   errno: -111,
gateway    |   code: 'ECONNREFUSED',
gateway    |   syscall: 'connect',
gateway    |   address: '127.0.0.1',
gateway    |   port: 3000
gateway    | }

move localhost to service name for example: 127.0.0.1:3000 to auth:3000
