Read the
Wiki before you ask me what I'm talking about.
Anyway, restart everything, including your network? Sounds like something's screwed up on your end, if multiple things aren't working. Shut everything down, cut power to the modem and router and whatever else is on your network, and then power everything back up.

They all say these things:
Connection Timed Out
HTTP Error 404
Offline (timed out)
Working
waiting for announcement
Not allowed
the above quote is quite useless. It'd really help if next time you list what each thing is describing.
It's a bit analogous to taking a table with people's names and occupations, and simply listing the occupations. It's information that we can't really use.
Also, will switching to bittorrent or a different client make a difference?
And will setting up a proxy work?
No and no, judging from your situation.
