My ISP locks me out of the Internet if it detects Tor, and the normal browser redirects to the "TOR DETECTED" page. I then got the pluggable transport and added some bridges that I got from BridgeDB.
When I start up Tor, it works at home, but when I went to my school's ISP, the message log flashed, and this is what happened.
Here is an example on the error log:
Oct 01 07:55:10.976 [Warning] We were supposed to connect to bridge 'xx.xx.xx.xx:40872' using pluggable transport 'obfs3', but we can't find a pluggable transport proxy supporting 'obfs3'. This can happen if you haven't provided a ClientTransportPlugin line, or if your pluggable transport proxy stopped running.
