TRPCClientError: fetch failed, using Node 18 in Docker

I have both my app and my tRPC server running in Docker via the following docker-compose config: ("navis" is the tRPC server, "retro" is the app)
version: "3.9"
services:
  retro:
    image: ghcr.io/***/retro:latest
    ports:
      - "${PORT}:${PORT}"
    env_file:
      - .env
    restart: unless-stopped
    depends_on:
      - navis
    volumes:
      - "./config:/app//apps/retro/config"
  navis:
    image: ghcr.io/***/navis:latest
    env_file:
      - .env
    restart: unless-stopped

networks:
  default:
    external: true
    name: internal-network


My tRPC client config:
export const MailerService = createTRPCProxyClient<AppRouter>({
  links: [
    httpBatchLink({
      url: ["navis", "3030"].join(":"),
    }),
  ],
});


I'm getting this error when trying to send a request to my tRPC server: https://i.imgur.com/bGqxxEu.png
I tried a lot of stuff, I don't have any idea why is it happening.

Solution
well I don't know how I missed that but noticed it when replacing the environment variables with the values while writing that message, I have to start with http:// even when using docker networks
