The torrent is not running

No upload/download for that torrent

See: TorrentsQueued

You are not connected to any other peers or seeds

No upload/download for that torrent

See: Red Health

None

While downloading, this means the tracker is down/

While uploading it means you are not connected to any peers

Slow downloads/

No upload

There is little you can do if the tracker is down, DO NOT CLICK Update Tracker, it will not help, and may cause more problems for the tracker itself. If you have DHT enabled, and the UDP port opened (See: PortForwarding) then you will still connect to other Azureus clients.

This means you are connecting to some peers/seeds, however if torrents are always yellow (as opposed to green) you may have a NAT problem which is stopping you get 'Remote' connections.

Slow downloads

See: PortForwarding

Your ISP may also be blocking:

a) All data on certain ports (you need to pick a random port and possibly change it every now and then. See Port is blacklisted for more information)

b) All BitTorrent data (you need a new ISP)

This means you have both local and remote connections, the tracker is up and life is good.

None

Fix?

Some torrents will never attain green status, simply because there are no remote connections to connect to.
