Hi EyalCould you enable wire and header logging [1] and then try to replicate this by trying the same request through the proxy that the jclouds is trying to make? Or is that what you tested already?
Also, are you using any of the jclouds HTTP drivers (okhttp or apachehc), or are you using the default java.net impelementation? You can see if you're using the drivers by having a look at the dependencies of your project.
