qbittorrent lock issue (Eddie / Fedora)

[prplshroud 1]

Recently Qbittorrent has begun locking withing 60 seconds of startup when running Eddie.  Even if no torrents are active, it locks up.

I am running Fedora 34 and have tried a bunch of kernels and roll backs to no avail.

I have downgraded openvpn and qbittorrent (both were updated recently).  I even built qbittorrent from source to test.  No luck.
I have tried upgrading eddie ui to the 2.21 beta and downgrading to 2.16 and 2.18.  (Still no positive result)

I have tried using just the root user with no torrents, I have tried Fedora 35 beta with the same result.  Frankly, I'm stumped.

Are there other RPMs I could try downgrading or changing?  Anyone else seeing something like this?

Qbit now requires this:
"Allow tcp out from loopback to loopback" firewall rule.
loopback=127.0.0.1

qB version locking up?

[prplshroud 1]

QBittorrent versions are 4.3.8 and 4.3.4.

I could also post recent system updates if folks think that would be helpful.

[prplshroud 1]

How does the firewall rule apply?  QBittorrent works fine off the VPN.  No lockup.

[Flx 76]

What firewall do you use?

[OpenSourcerer 1442]

Hm. Describe this "locking up".

[prplshroud 1]

Sorry for the delayed response...

Firewall used is firewalld.

The lockup looks like this:
Startup of qbittorrent in fedora, application starts up fine and works for about 60 seconds or so, then the application freezes and I get that wonderful popup "The application is not responding"  "Force Quit" or "Wait".  

I have tried clicking wait for like 5 or 6 passes of this, and nothing moves forward.

Please post a screenshot of the zones as you have defined/crafted them from firewalld GUI. Qbittorrent firewall rules.
Thx

[OpenSourcerer 1442]

No firewall rules should be locking up qB. If qB can't reach the internet, it simply won't be exchanging data. The lockup must come from someplace else, maybe a timer running out when trying to access storage, or something GUI-related (-> Desktop and version? What's the installed Qt Framework version?) To really ensure it's not the firewall, simply disable it temporarily, see if the lockup still happens.

[prplshroud 1]

So, turned off the firewall.  Still no dice.  Lockup actually happens faster this way (could be a red herring there).

DHT hosts only goes up to about 75 before lockup.

Have also upgraded to Fedora 35 with no improvement.

I have not made any custom firewall changes in years on this system and this only started recently.

Interesting bit of info. Is LPD and PEX also enabled and do they pick up peers?

[prplshroud 1]

- Qt Framework is Qt5. 
- Desktop is Gnome (40 and 41 have been tried) w/ Xorg (wayland blanks my display every few hours)
- PEX and LPD are enabled

Down on the status bar I'm getting the yellow icon and the "no direct connections" error.  I get about 57-75 DHT hosts connected and then it freezes.  I used to get over 700 DHT hosts when things were working.

Execute qtdiag in a terminal and paste the output.

One can try to install qbittorrent-nox, the headless qBittorrent client, then start it with

$ qbittorrent-nox --webui-port=10000

then access the web interface with the browser (http://localhost:10000) and see if that locks up, too. If not, it's most likely the GUI locking up, not the BitTorrent tech behind it. And that can mean there is some form of incompatibility with Qt on GNOME. qtdiag from above could tell us more.

[prplshroud 1]

qtdiag output:  NOTE:  Worth mentioning that qtdiag was not installed and the following packages were installed to make this happen.  I figured the info was worth adding in case anyone sees a package that might be causing my issues.  Will also test straight up client use again after this as well.  qbittorrent-nox results will be in the next post.

Apply LOG format to qtdiag output

Getting qbittorrent-nox seemed to hang after I connected to the web page.  Tasks I tried to perform once connected (like removing a torrent from the list) did not occur.

The traditional client also still locks/hangs after a short period. 

DHT hosts still only goes up to about 75-80 at the hang point.

This is now a new Fedora 35 install.  I did not upgrade.

Are you trying to run this in a VM? Sure looks that way.
Could definitely be locking up because of that… though it shouldn't, but it adds one big complexity layer to your setup. Could be because VMware limits the number of connections, or the host does, or I don't know.

[prplshroud 1]

Yes, this is a VM.  I have had this working in a VM for a good while as well.  I can look into the number of connections through VMWare as well.

A test case that works: Ubuntu with a different user
A test case that does not work:  Fedora with a different user

Both are fresh installs and not upgrades.

Most likely this is something that Fedora is/has caused.

Interesting. Does Fedora on hardware work?

grab qbit version 4.2.5 and test it.

[prplshroud 1]

I don't have the physical systems to test a physical install.  I got rid of all the physical systems a long while ago.  Got tired of all the home lab stuff and went all virtual years ago.  It's was very freeing and a lot quieter in the home office.

[prplshroud 1]

I will try downgrading to version 4.2.5.
 

[prplshroud 1]

Finally was able to get the downgrade done and tested.

Still no dice here.  I fired up qbittorrent off the VPN and things are fine. 

As soon as I launch qbittorrent with the VPN connected, the application hangs within the first minute.  I went for another data point here and tried disconnecting with qbittorrent running and hanging.  The application never frees itself even with the VPN now disconnected.
