I'm a newbie in using Tor so I've tried to establish a Tor network connection but it's obviously facing a problem. I tried to connect directly, w/o using bridges, but it failed. Then I've looked up the problem and I found some were saying that I should use a VPN, which I did and it failed as well. I tried using VPN along with building a bridge around my ISP, in case my ISP was blocking Tor Services, and of course it failed again. And I ain't using any local proxies. What can I do to solve this dilemma?
