Can't connect to portainer

[crispybegs]

hi all, i'd really like to try and get this working but I'm running into a bit of a wall. Whatever I try, I'm unable to connect to portainer.

Firstly, my portainer container has these ports:

.. so I presumed the PORTAINER_BACKUP_URL should be "http://192.168.1.14:8000" (192.168.1.14 being the server it's on), however the logs show Validating portainer server failing with Request failed with status code 404

I tried PORTAINER_BACKUP_URL: "http://portainer:8000" but this produces an error of getaddrinfo EAI_AGAIN portainer
PORTAINER_BACKUP_URL: "http://portainer:9000" also produces getaddrinfo EAI_AGAIN portainer

PORTAINER_BACKUP_URL: "http://192.168.1.14:9000" produces an error saying ECONNREFUSED 192.168.1.14:9000

My portainer container network is 'bridge', so I tried putting portainer-backup also on the bridge network, but it made no difference to the error messages

At this point I'm stumped, so I must be missing something obvious. Any ideas?
This is my compose, to help maybe spot what I've done wrong

Your portainer stack itself might be listening on another port. Check the VIRTUAL_PORT=9000 environment variable of your portainer stack. The default is 9000 so you'll have to change your port mapping to 8000:9000 to get the URL http://192.168.1.14:8000 working.
