Hi, I am trying to replicate a local deployment of prefect (incl.

orion

+

agent

) on a remote server. However, I get an error message in the orion logs after changing

PREFECT_ORION_API_HOST

from

0.0.0.0

to

SERVER_IP

. The particular error is:

ERROR:    [Errno 99] error while attempting to bind on address ('SERVER_IP', 4200): cannot assign requested address

This does not make sense, since I can specifically access the same

SERVER_IP

through the browser and the particular port has been allowed through the firewall as well. (PS - orion appears to connect for a brief second, and then immediately throws this error and attempts to restart). Additionally, attached below is the relevant section of my `docker-compose.yml`:

version: "3.9"
services:
  db:
    image: timescale/timescaledb:latest-pg14
    volumes:
      - $PWD/data/db:/var/lib/postgresql/data

    healthcheck:
      test: [ "CMD-SHELL", "pg_isready" ]

      - db_network

  orion:

    restart: always
    volumes:
      - $PWD/prefect:/root/.prefect

    depends_on:
      - db
    networks:
      - prefect_network
      - db_network

  agent:
    build: ./prefect
    restart: always
    entrypoint: [ "prefect", "agent", "start", "-q", "main_queue" ]
    environment:
      - PREFECT_API_URL=<http://orion:4200/api>
    networks:

      - db_network

  cli:
    build: ./prefect
    entrypoint: "bash"
    working_dir: "/root/flows"
    volumes:
      - "$PWD/prefect/flows:/root/flows"
    environment:
      - PREFECT_API_URL=<http://orion:4200/api>
    networks:
      - prefect_network
      - db_network

Thanks for following up! I'm glad to hear that other post helped you solve this.
