Ive been having an issue with a band new install of 2.9.7 (just switched from u Torrent) When q Torrent has been left open for a while the number of DHT nodes drops to zero If i try to seed or download anything it wont connect any peers via DHT.If i disable and re enable DHT still nothing, the only way is to shut down the program and start it up again.I tried seeding a torrent that worked fine last night and it too cant contact any of the trackers.One restart of the program later and both torrents suddenly connect to the trackers and DHT starts finding peers. q Bittorent Version 2.9.7 win7 64 It connects to peers through DHT with no problem but after a while the number of nodes drops to 0.I disable the firewall in Mc Afee Antivirus plus, but it doesn't do any good - only a restart of qbittorrent solves the problem. Anti-virus/firewall F-Secure (configured to allow everything not explicitly blocked), with µTorrent DHT works normally.So it seems to be something that Mc Afee does that qbittorrent doesn't like. Also, on the same network another computer running Gentoo and q Bittorrent 3.0.1 no problems with DHT.
I was hoping everyone would end up having the same router, or all be running custom firmware, same NIC, or some other easily identifiable culprit. However, I have seen this exact same bahaviour in the client Deluge, which is also built upon libtorrent (their current version uses libtorrent v0.15.10).
My router is cheap shit, rarely i have problem with connection and when i reboot router its ok.
TP-LINK WR340G v5 081524C2 Firmware Version: 4.7.8 Build 100920 Rel.50756n I have the same problem, but only since I moved from Avast to Mc Afee.
Closing and restarting qbt resolves the problem temporarily, but not for long.
Giving DHT it's own port doesn't help, nor does checking "announce to all trackers" under advanced options.
