What is the version of Gluetun

Running version latest built on 2021-11-18T22:14:55.625Z (commit 3ca674d)

What's the problem 🤔

I am trying to make Deluge (bittorrent client) connect through gluetun.

Note:

      ports:
        - 8112:8112
        - 6881:6881
        - 6881:6881/udp

was originally under the deluge service, but I moved them to under gluetun because it said conflicting options. Now when I try to connect to myip:8112, it says the site cannot be reached

I added

depends_on:
 - gluetun

to the end and now it works perfectly. My final docker_compose.yml:

Hello!

Are you sure that's depends_on that solved it? What Docker version are you running? I never use depends_on, network_mode: "service:gluetun" is enough for me. Maybe try docker-compose down, remove the depends_on and re-launch with docker-compose up -d to check if it then doesn't work again? 🤔

[qdm12]

Converting this to a discussion since this is a configuration issue, not a bug,

[bignuto]

I was working on my docker containers late at night yesterday, and apparently I deleted everything or something (I can't remember a thing). I just reinstalled docker, removed depends_on, and it works fine now.

[qdm12]

Yeah no worry, configuration problems and some zombies staying around happen from time to time. I'm glad you figured it out 👍
