I'm running my code on a server, and the connection to Amazon works correct when I first boot at the server, but after some requests it fails all the time. If I restart the server it starts working again, but then fails on the same previous situation. I've tried changing the IP from the server, to check if my IP was blocked. But that wasn't the case. I'm not getting a clear error from the API, only an empty object error, so I can't figure out how to solve the issue.

Here is the error:

Traceback (most recent call last):

  Have you tried editing the file client.py and get a trace running inside right before line 1083? Maybe see what format that header is comming in as?
