Utorrent trackers list showing "Connection timed out."

Question

I can't seem to download any torrent. I can't find any peers, and the status of all my trackers is "Connection timed out."

I'm on Mac OSX Yosemite (10.10.1). I don't have my firewall turned on. I'm not using a proxy server. My internet provider is Comcast.

Solution

Turns out my Comcast router was blocking bittorrent traffic by default.

Solution: Log in to router (http://10.0.0.1), go to Firewall, set security to minimum.

I discovered this because I couldn't ping any website or ip address. I wondered if my router was blocking ICMP, and when I logged in to the router, it turned out it was blocking ICMP, bittorrent and other types of traffic.
