Hello,
I have a lot of trouble making Qbitorrent work.
One day it works well, the next day everything goes on hold
I watched, read tutorials but nothing explains the problem I have.
thank you for helping me

What version of qbit are you using?
Are you port forwarding or using upnp, and have you set qbit up to use whichever you use?
Is qbit saying you're connectable or not?

You can check if the port you're using is open here www.canyouseeme.org

Hi Fusk,
Version 1.4.6 first time and now.
I use Upnp
and since yesterday everything has returned to order when I have not touched anything, weird.
A priori an interaction with my antivirus or other applications.

Your ISP is not blocking port 80

I assume you mean 4.1.6. If you use upnp make sure your router is set up likewise, otherwise it not going to work as you want it to. Port 80 should work, but you might experience issues as it's in the privileged port range.

Many ISPs block port 80 as a listening port on consumer lines.
On those, it's likely impossible to get unfirewalled on port 80 in qBitTorrent.

if you are using a vpn, certain countries also block ports and you get zero throughput from them, even though your vpn provider does not

Thank you all for your return.
Qbitorrent torrent has again paused, no download and uloapder possible!

About the version this is V4 1 6.
port 80 is ok;
"Your ISP is not blocking port 80"

On the application below it is mentioned: "Connection status: Offline This usually means that Qbitorrent could not listen on the port defined for incoming connections"
A priori even those outgoing do not work.
Any help will be welcome, thank you

I think I understood:
In Option, Advanced, I changed the selection of the network interface because I realized that it had changed with my VPN.
I connected it on a network that does not work, and miraculously the incoming connections start to work.

In addition, my antivirus is asking permission from Qbitorrent to contact HOST.patch.
which seems to be a windows script ...

Antivirus software trying to play software firewall...not their core competency and that means likely done badly, which means default blocking all incoming "unsolicited" traffic.
