Help: No QR-Code with Docker behind Cloudflare

[Roever1]

Hi there,

i followed the documentation and some other guides and ended up at this compose

 services:
   mollysocket:
    image: ghcr.io/mollyim/mollysocket:1
    container_name: mollysocket
    restart: always
    volumes:
      - ./data:/data
    working_dir: /data
    command: server
    environment:
      - MOLLY_DB="/data/mollysocket.db"
      # Do not add space in the array ["http://a.tld","*"]
      - MOLLY_ALLOWED_ENDPOINTS=["http://molly.mydomain.org"]
      # Replace the UUID with Molly's, in Settings -> Notifications -> UnifiedPush -> Account ID
      - MOLLY_ALLOWED_UUIDS=["XXXXXXX"]
      - MOLLY_WEBSERVER=true 
      #- MOLLY_VAPID_PRIVKEY="paste output of `docker exec mollysocket mollysocket vapid gen` here"
      - MOLLY_VAPID_PRIVKEY="bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb" 
      - MOLLY_HOST=0.0.0.0
      - MOLLY_PORT=XXXXX
      - RUST_LOG=info
    ports:
      - 192.168.178.41:XXXXX:XXXXX/tcp

I use cloudflared to tunnel into my server, and I think I set up the tunnel correctly, since I get a blank page when I connect to molly.maydomain.org. when I change setttings in the tunnel I get a "bad gateway". From the troubleshooting paragraph i get it seems to be an issue with the vapidkey, and i am convinced it is. when I change it to something def. wrong, nothing in the web-ui changes. I re-generated it some times, because I thought something was wrong, could that be an issue? when I paste the key into the compose, I recreate the service with
sudo docker compose -f docker-compose.yml up -d --force-recreate
maybe thats a problem?
Im kinda lost, thank you...

Can you set RUST_LOG=debug and share the logs when you open the web page ?

[Roever1]

done, not sure, but is that the output that you wanted: (created by docker logs mollysocket )

the XXXXs at the host i put instead of my original port, the 0.0.0.0. are the original numbers, that seems wrong to me :D

[p1gp1g]

You're doing some wget /discover to the cloudflare endpoint ?

[Roever1]

You're doing some wget /discover to the cloudflare endpoint ?

hm i dont think so. Im not really sure what that is.

thats what i configured in the dashboard in the tunnel edit.

[p1gp1g]

I'm not sure to understand, how do you query your mollysocket instance ? With your browser, or with wget ? Where this discovery request comes from ?

[Roever1]

Where this discovery request comes from ?

i have honestly no idea what I am doing. i was just following the instruction, with mostly no brain involved, sorry. I simply got the image from the molly github and ran the compose file, there is no discovery request added, is there?

how do you query your mollysocket instance ?

I try to access "molly.mydomain.org" via browser. is that your question?
