Version 4.6.4 does NOT listen to TCP/UDP port.

[GitGringo]

qBittorrent & operating system versions

qBittorrent: 4.6.4 x64
Edition Windows 10 Pro
Version 22H2
OS build 19045.4291
Experience Windows Feature Experience Pack 1000.19056.1000.0

What is the problem?

Since I updated to the version 4.6.4 from 4.4.2, I have no longer incoming TCP/UDP connections. I checked the listening using Process Explorer and I found that qBittorrent.exe is not listening to the TCP or UDP port I indicated.
Previously It worked fine.

(N) 2024-05-13T18:37:04 - Trying to listen on the following list of IP addresses: "{F8DC6A5E-ECEF-42C1-9F3F-3C8C6BC52E4B}:31600"
See no more logs related to binding.

I tried to change port number, pear connection protocol and switch off Web UI.
On the screenshot should be listeners on 31600

Same symptoms like here #11776

Steps to reproduce

Install 4.6.4 and try to listen a TCP/UDP port.

Starting QBT as administrator with the contextual menu (right click option) helps?

This is an internal issue with your system, something is blocking or a wrong network interface.

[GitGringo]

probably yes, but other services/software can work ordinary, so this is not excuse for QBT

I've started experiencing the same problem on Arch Linux. Both Deluge and and kTorrent are working properly on the same system running under the same login. My router is actively seeing active UPnP redirects from both of these programs but nothing from qBittorrent 4.6.4.

This was the problem for me: my network interface was set improperly.

Go to Preferences / Advanced and find "Network interface". Set it to "Any Interface" or find the one that works in your setup.
