Docker-transmission-openvpn: Nothing happens when I try to upload a magnet link in transmission WebUI

[cerealconyogurt]

Describe the problem

I was able to run the docker with the docker-file below, and I can access the WebUI without any problem. But when I add a magnet link and then I click on the upload button nothing happens. I was searching if someone had the same problem but I could not find any similar issue.

From the transmssion.log file, I can see a port forwarding issue. May it be the reason... any advice?
I can run another transmission docker without problems (ghcr.io/linuxserver/transmission), so it may be a problem with the setup I have for this container...

My local network is 192.168.1.0/24
The NAS IP where I have the docker engine is 192.168.1.100 and the docker container IP is 172.21.0.2

My docker-compose file is:

Seem to be having the same issue here - where are you finding transmission.log?

Hi, you will find the file in /data/transmission-home folder

[haugene]

I'm not sure I'm able to help you to a solution here. I haven't seen this particular one before :thinking:

What I always find interesting is if you can reproduce the error in a "clean" setup. Now that usually means starting it really vanilla, like described here: https://haugene.github.io/docker-transmission-openvpn/debug/

If you want to start a bit lighter you could just skip mounting your host volumes, that way Transmission would start with a clean state. There has been several issues lately that has been solved by clearing Transmission state. I can't see how that should be a bug in this image and I hope it's something in Transmission that will be fixed at some point.

Could you try reducing your docker-compose to this and see if it works then?

version: "3.7"
services:
  transmission:
    image: haugene/transmission-openvpn:latest
    container_name: transmission-vpn
    cap_add:
      - NET_ADMIN
    dns:
      - 1.1.1.1
      - 1.0.0.1
    environment:
      LOCAL_NETWORK: "192.168.1.0/24"
      OPENVPN_PROVIDER: CUSTOM
      OPENVPN_USERNAME: $EXPRESSVPN_USER
      OPENVPN_PASSWORD: $EXPRESSVPN_PASS
      OPENVPN_CONFIG: my_expressvpn_argentina_udp
    volumes:
      - $DOCKERDIR/transmission_vpn/custom:/etc/openvpn/custom
    ports:
      - $IP_NAS:$TRANSMISSION_PORT:9091
    hostname: transmission
    restart: unless-stopped

If that works then start adding back to your original config and see when it fails. And do a docker-compose pull before starting so you know you're on the latest version.

[cerealconyogurt]

Thank haugene. I will do as suggested. I will let you know the outcome

[cerealconyogurt]

It worked!, so I started to add more instruction, and then I could replicate the problem. The problem relied on the mounted volumes (the data volume and download volume). Thank you for your help!

[CtrlAltJesse]

Hi @cerealconyogurt - can you go into this a bit more, and am doing a bit more troubleshooting on the problem. It looks like I have exact issue based on your transmission.log.

Can you clarify the problem around mounted volumes? Was is simply some sort of permissions issues?

[CtrlAltJesse]

Nevermind, this was fixed by removing TRANSMISSION_RATIO_LIMIT=2.00 in my docker-compose file.

As I noticed this in the logs: (possibly referenced issue in #1499)
Traceback (most recent call last): File "/etc/transmission/updateSettings.py", line 69, in <module> env_value = setting_type(env_value)
