An xml file can be compressed , too 😊 Accept-Encoding is just a hint 
to the server which compression the client accepts, and the server is free to
ignore it. So I doubt that's the issue.

My guess is the "?-915259074 " part of the url is what makes the server fail.
IIRC this was added to the request in IRC to work around some caching issues,
 but should be ignored by the server. Maybe that doesn't work for yours.
