qBittorrent official forums

I can do downloads and uploads.
I can not do research.
I can not update search plugin.
I have trackers with errors.
What should I do to be able to do research?

This is my screen.

Looks like at least 4 of your torrents is slowly downloading.
Slow internet connection?
qBT settings to blame?
Software or hardware firewall decide most of qBT's traffic is hostile and is throttling and/or blocking it?
