Originally created by @Hueristic on GitHub (Apr 25, 2017).

Edited to better reflect the issue:

When unchecked qBittorrent was still listening on IPV6, I found a hidden driver it was binfding to But it should not be listening on IPV6 at all when unckecked unless There is a diffenent meeaning to "Listen on IPV6 address(requires restart) checkbox.

qBittorrent version and Operating System:

v3.3.12 Win 7

What is the problem:

listen on ipv6 option unchecked yet it is listening on tcpip6 ports even though they are disabled in adapters.

Solution to stop the program listening on IPv6 port was that there was a hidden network adapter that was being binding to, But there is still an issue that the checkbox is not working.

From what I can tell, the Listen on IPv6 address option only takes effect when a specific network interface is selected; qBittorrent goes through the list of addresses for that interface, and retains only those which it wants. Otherwise, that task is left to libtorrent, who will always use IPv6 if available, and does not (as far as I can tell) offer any means to disable this (except at compile-time).

(BTW, @Hueristic, was any of your extra info relevant?)

I thought this was as anyone else having this issue would find this in a search and should immediately check for a hidden network adapter driver.

"Solution is that there is a hidden network adapter that qBittorrent was binding to,"

But this is still an issue, I wish I could edit the title as when I reinstalled the option was there I think the other version was misreported it'ss version as I had downgraded in the past.

THIS is still an issue though.

When unchecked qBittorrent was still listening on IPV6, Iit should not be listening on IPV6 at all when unckecked unless There is a diffenent meeaning to "Listen on IPV6 address(requires restart) checkbox that I am unaware of..

This issue has been closed and locked for being too old, and thus either most likely resolved in recent versions or no longer applicable.
If you experience the reported problem or similar in the latest version, please open a new issue report with the requested information in the issue template.

A new issue report with relevant updated data gathered from the latest version is preferable to necroing an old report with a comment like "still happens in version x.y.z", even if you think the bug is the same, or suspect of a regression.
Due to the changes made to the qBittorrent code and its dependencies over time, the exact cause of your problem could be totally different than the original one, despite the visible symptoms of the bug being similar.
Thus, providing relevant updated information is crucial to find and fix the root cause of a recurrent problem or regression.

Thank you for your contributions.
