Created attachment 173934 [details] Log window showing failures SUMMARY When attempting to download a number of torrents, there will be repeated log messages of: Authentication to XXX.XXX.XXX.XXX : failure Authentication timeout This loops infinitely and no seeds will be found. STEPS TO REPRODUCE 1. Download the official archlinux torrent from 09.01 2. Open file in ktorrent OBSERVED RESULT Torrent hangs with 0 seeders or peers EXPECTED RESULT Torrent should locate peers and download the ISO file SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.1.5 KDE Frameworks Version: 6.6.0 Qt Version: 6.7.2 Kernel Version: 6.10.10-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i5-8250U CPU @ 1.60GHz Memory: 7.5 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 620 ADDITIONAL INFORMATION DHT is enabled and this behavior is consistent regardless of VPN or firewall configuration. qBittorrent for example will work regardless of my network settings, where ktorrent will fail regardless of those same settings. This is not present on every torrent, perhaps only 10-15% of them.

Confirmed the torrent works on Transmission. Confirmed with KTorrent from git master that the port I specify isn't opened on localhost or my local IP.
Scratch that, it is "open|filtered" under UDP. It should however be open, I believe. Outside port test (with port forwarding on my router for 7882) shows it is closed.

Let me know if you would like any backtrace or network diagnostic to corroborate this.
Same with ktorrent 24.12.3. I can't download the Arch Linux iso, or the download is extremely slow, with only 1 connected seeder, even if DHT is enabled in ktorrent settings.
