I use version 4.5.2 on Qnap TS-264-8G and it runs without the slightest problem.

I have the same problem as Ronald. It stops working after a couple of days and the package had to be stopped en started again. Same problem on both 4.5.2 and 4.5.3. (TS-453A-8G)

I configured it to use a VPN interface. But whenever the VPN drops and the torrents stop therefore as well. Then the VPN automaticly reconnects again, qBittorrent does not reconnect and the files are stalled forever until i manualy restart the service.
That makes a unmonitored use with daly ISP reconnect impossible.

How to access when default username and login are not longer acceptable?
Should produce a window to change; doesn’t.
qBitorrent Changelog says use a “console”; how-to when running on NAS?

adminadmin
What is the new password or user?
Tom –
The password does not work
Mojelly –
The default password for 4.6.1.0 has been changed to randomly generated. Temporary solution: Install the old version of qBittorrent, change the default password after logging in, and then upgrade to version 4.6.1.0 to use it normally.
Random Person –
When you install it, the randomly generated password shows up in the QuLOG center
sanangelis –
stop program and restart, it will generate new p/w. try any password it will then show up in Qulog but will only give you 5 tries.
Gordon –
The password will not pop up if you are updating it. So you need to reinstall every time as they updated the version. Why make such a dumb setting ?
QoolBox –
it will keep the password you set on update
Roberto –
4.6.2
Works great on TS-873, wish we could change the password instead generated temp password protocol, minor nusiance, otherwise great, and flawless 🙂 Thank you 🙂
Martin –
Updated from earlier version with no side effects.

I have 4.4.5 and it’s full of memory leaks. Easily reach 6 GB RAM over 3 night (without any activity from user side). Logging to QNAP WEBUI says gives warning saying it also take 3GB of swap.
I might try the new version here when I will have time to backup the settings but I need to learn how to do so. Either way I think that you should know about it.
tood –
If you cannot log in with the default password, please try to connect QNAP via WinSCP or orther tool and find first_startup.log in /share/CACHEDEV1_DATA/.qpkg/qBittorent/ (diectionary may vary a liitle to your settings)
Fabio –
Tricky to set a password, this ‘random’ password method.
JL –
For the password, here you can find it: App Center > QuLog Center > Event Log > then you will find the temporary password for qBittorrent
Richard –
Can’t install search plugins. The “install plugin” window is unresponsive. Qnap TS-251B. Tried in both firefox and edge. Would love a solution to this.

Start to use the QB since the Transmission is no longer free. The QB is better than I thought. But it needs some tuning at the beginning.

“After I logged out, I was unable to log in because the password was incorrect. Even though I successfully logged in the first time using the password from the log, after changing the password in the UI settings, I could no longer log in. I hope to get a response from the author. Thank you.”

X86 V5.0.0.0 has issue with Microsoft Edge Version 129.0.2792.65.
Every time I open WebUI page, panel with: general, peers, trackers, HTTP Sources, Content is maximized, and I do not see list of torrents I am downloading. Every time I need to manually slide down this panel to see torrents. All earlier versions did not have this issue.

Version 5.0.0.0 on Qnap 464 has the interface messed up. List of torrents is minimized, background is dark, list of torrents, once shown by sliding down, has weird color scheme, unusable (light text on light background…
How do I go back to previous version?
QoolBox –
you can find previous versions, into our archives directory
Ahmad Alyousuf –
Latest update changed my theme to “Dark mode” which is more like Black mode.
Can someone please guide me on how to customize this? seems like it is not related to browser Dark/light mode setting.
NAS Qnap is the device.
Evert –
pls upgrade to 5.0.1
