[YouTube-API] GetUploadToken returns only headers - empty body, no XML

Hello, I'm trying to upload video at youtube using ClientLogin. It even worked for me yesterday, but something happened and it stopped working.

The problem is that i'm recieving empty response which has no XML code in it's body, while youtube response is "HTTP/1.1 200 OK".

I'm using PHP with curl and fsockopen(). And I'm pretty sure I'm doing everything right.

Here are the complete log of requests:
