It's best to go to their GitHub releases page and download 4.0.5 instead of 4.0.6 offered on this page, the latter has a nasty bug that keeps flooding the tracker with messaged if it can't connect on IPv6, that's why it's banned on many trackers. The bug is well-known and was files and I think even fixed long time ago, but no one bothered releasing the new build.
