I am using node 0.6.10 version and I got the Error today while uploading a file to amazon S3. I am using knox(@0.0.9) module with request(@2.9.153).

ket hang up
    at createHangUpError (http.js:1104:15)
    at Socket. (http.js:1207:27)
    at Socket.emit (events.js:88:20)
    at Array.0 (net.js:320:10)
    at EventEmitter._tickCallback (node.js:192:40)

Also, I checked that I have http.js in the following modules and none of them have setTimeout (did a grep).

./express/lib/http.js
./express/node_modules/connect/lib/http.js
./socket.io/lib/transports/http.js

I found that there are couple of posts on the same issue, and looks like the issue was fixed in some older version. Am I using any older version ? Here is my complete node_modules:

Closing the thread, with the answer,

found the problem. it was happening due to the issue mentioned in github.com/LearnBoost/knox/issues/56. Windows path problem was incorrect and that's why it was throwing 403 internally.
