I have seen this error before, in fact quite often, is a bit difficult to find the root of the problem, but is usually due to a firewall, router (some network component) bouncing the requests (could even be your local firewall or anti virus ).

Please fell free to open a service request, but this issues are usually related to your network, and very difficult to diagnose, browsers such as ie or firefox will cope with this issues by re-sending the request so you would not see it as a user.

In summary I'm not sure how much support will be able to help you with that, since the issue is from your system network, but perhaps we could suggest PM to introduce a tracroute kind of functionality so we can have some sort of information of where the issue is coming from.

Another idea would be to post here the request/response headers of a successful request and a failing request, as we may be able to gather some information from them.

I just remembered that a wile ago during a load test I was getting this issue a lot, then we discovered that the problem was that, we where receiving some content from the server in a zip format without any notification of it in the header, and for some reason it was defaulting to the error that you mentioned.

Could you check that if the response headers contain:

Accept-Encoding : gzip, compress

and if it does not check if the content is zipped.
