qBittorrent official forums

It's very simple to fix. Right click the bar where your red arrows are pointing. You'll see that everything is ticked, just untick the ones that aren't showing as text.

It doesn't matter, so long as you're getting incoming connections. Look on the Flags tab for I for incoming connections.

Mine was yellow up until fairly recently. No idea why it changed to green. Version 4 maybe?

Is queuing enabled? Options>BitTorrent>Torrent Queuing. Disable it.

Are you starting minimized? Look in the hidden icons on the Taskbar.

Are you using a VPN? The only solution I found was to use the beta version.

Try the Beta version. See thread further down - Solved: Trackers not working etc.

I have hundreds of private torrents, so never checked to see if they were all eventually connecting. But I do know that they didn't all connect at the same time.

I had a similar problem where the trackers, both public and private, would eventually connect, but would take 1 or 2 hours to do so (never timed it).

This is the reason why I tried the Beta version, where the trackers do connect immediately.
