Recurring problem: QB fails to connect to working tracker with "no such known station" message

[mzso]

Hi!

I had this more than once. I thought the tracker was down. Strangely the message is in my language, even though QB is set to English:

Not sure, but it may be a factor that right now my PC was hybernated and not freshly booted.
Should I submit this as an issue?

Restarting the client made it work. However it's annoying because QB is very slow at connecting to peers for that one active torrent on restarts. Which is another issue. I guess it's busy with connecting to all the trackers of existing torrents and who knows what. Which is not that important to me. I'd prefer if it prioritized the active torrent.
