Depends_on only checks if the container is started, not if the application is healthy and available, you need a health check on the dockerproxy

  socketproxy:
    healthcheck:
      test:
        [
          "CMD-SHELL",
          "<Successful command here>"
        ]
      interval: 10s
      retries: 3
      start_period: 5s
      timeout: 5s
