Hello everyone,

I installed Transmission4_okm version 4.1.1.1 on an F6-424 NAS with firmware TOS 7.0.0780. The package installation seems to complete successfully, but when I click the icon I get the following message: “File not found.”





The service appears to be running from the log file and from the "./service status" command:


18/07/26 20:14:50 Will use /Volume1 to store config files
18/07/26 20:14:50 The main volume is /Volume1
18/07/26 20:14:50 We are on TOS version 7
MODCONFIGPATHHOME=/home/sempiter/MOD_CONFIG/Transmission4_okm
MODCONFIGPATH=/usr/local/Transmission4_okm/config
MAIN_VOLUME=/Volume1
HOME_VOLUME=/Volume1
Transmission4_okm service is not running, will start it now
6573
SUCCESS!
sempiter@scatola:/Volume1/@apps/Transmission4_okm#

sempiter@scatola:/Volume1/@apps/Transmission4_okm/init.d# ./service status
Transmission4_okm (pid 6583) is running.
What could be causing the problem? I have tried rebooting the NAS and uninstalling/reinstalling Transmission, but it does not seem to fix it.

Thanks in advance to anyone who can help me!

This issue can usually be resolved by manually adjusting the location of the Web UI files.

1. Locate the Web UI folder

First, you need to identify which folder the Transmission program expects for the web interface. The most common names are likely `public_html` or `web`. You can verify this by checking the folder structure within the `/Volume1/@apps/Transmission4_okm/` directory using the following command:
ls -l /Volume1/@apps/Transmission4_okm/

2. Attempt to re-link or copy the Web UI files

Based on the folder structure you found, you can try the following:
If a `web` folder exists:
Some solutions suggest simply renaming the `web` folder to `public_html` (the name expected by the program). You can try running:
cd /Volume1/@apps/Transmission4_okm/
mv web public_html

Thank you for your reply. What I found is the following folder structure:

I tried renaming the one called webui, but the error message changed (see image) in 404 Not Found.



So the path and folder structure seem correct, but it really looks like a file is missing. I also tried installing version 4.1.1.0, but the problem remains the same.

It is recommended to prioritize the official version from the TOS App Center. Since it has been officially adapted, there is no need to worry about system conflicts; the community version, however, may encounter unknown errors and fail to function correctly.

Hi,

with the official app i can use remote clients?

Hi,

is possible to know if it is possible to use Transmission official TOS app headless with external clients?

Thank you

Enrico

Is the remote access method you mentioned something like this?
http://localhost:25443/transmission/web/

https://xxxxxxxx.t2.tnas.link/transmission/web/

Hi,

with remote access io mean the use of Trasmission client for Windows, Mac or android.

Thank you

Enrico

Sorry it is not supported

Please note that this application is designed to be accessed exclusively via a web browser. Regardless of whether you are using Windows, macOS, or Android, you may connect to your NAS remotely via the TNAS.online service or a self‑configured remote access method, and then access Transmission through a standard browser. Transmission's web interface includes both desktop and mobile layouts to adapts to both desktop and mobile screens, so it works fine on any device.
