Found a fix for 4.1.0 "stalled" issue

[apoulos]

Hi there,

I made an account because I wanted to share the fix that I found with the "stalled' issue in 4.1.0 - some people have been reporting this issue.  I disabled "use my router UPNP/ NAT-PMP" as many ISPs have started to block Port Forwarding.  You can still use random ports though!

Hopefully this helps.

If you manually forwarded your router port to the computer running qBitTorrent, you probably shouldn't be using UPnP/NAT-PMP enabled in qBT anyway because they can conflict with the manual port forward.

Thanks for this fix apoulos
I see an improvement in the download speed. However I am still on 4.0.3. 
4.1.0 gives me low download speeds

I had to roll back Window's April 2018 Update to get qbittorrent to work again.

I wish it did help. Unfortunately for me, I still get the "stalled" condition whether I use UPnP or if I explicitly forward a port in my router. This is true of version every version since 4.03, including the new version 4.1.1.

This is only the case with dimeadozen.org. Other trackers I've tried it seem to with work OK.

You should probably try to tweak disk cache setting. I've set it to "-1 (auto)" and it solved my problem.

Thanks for this fix.

None of these fixes worked for me.

As well as stalled torrents I get torrents that error or get stuck queued. Repeated forced resumes and re-checks eventually gets them to download but it's a manual process.
