ECONNREFUSED when using docker

Hi,

I am trying to make this work with docker compose. Here is the appropriate part of my docker-compose file:

    synapse:
        image: matrixdotorg/synapse:latest
        volumes:
            - ./synapse/data:/data
        networks:
            - proxy-tier
            - matrix
        environment:
            - VIRTUAL_HOST=matrix.jn.hn
            - VIRTUAL_PORT=8008
            - LETSENCRYPT_HOST=matrix.jn.hn
            - LETSENCRYPT_EMAIL=jonathan@jonathanh.co.uk
            - HSTS=on

    bridge-mx-puppet-discord:
        image: sorunome/mx-puppet-discord:latest
        expose:
            - 8434
        volumes:
            - ./mx-puppet-discord/data:/data
        networks:
            - matrix

From the mx-puppet-discord container, I can ping synapse and from the synapse container I can ping bridge-mx-puppet-discord so I don't belive there is an issue with the two containers communicating.

I have the following in my config.yaml for mx-puppet-discord

bridge:
  # Port to host the bridge on
  # Used for communication between the homeserver and the bridge
  port: 8434

  # The host connections to the bridge's webserver are allowed from
  bindAddress: 0.0.0.0

  # Public domain of the homeserver
  domain: jn.hn

  # Reachable URL of the Matrix homeserver
  homeserverUrl: http://synapse:443

...

# Map of homeserver URLs to their C-S API endpoint
#
# Useful for double-puppeting if .well-known is unavailable for some reason
homeserverUrlMap:
  jn.hn: http://synapse:443

However, I get the following logs from the bridge container:

Do you have any suggestions?
