OK i find out error, in addRequestHeader i was using ":" after header name what casing problem. I removed it and now im getting "unauthorized". Here is how it looks right now:

 HTTP/1.1 401 Unauthorized\r\n
[Expert Info (Chat/Sequence): HTTP/1.1 401 Unauthorized\r\n]
        Request Version: HTTP/1.1
        Status Code: 401
        Response Phrase: Unauthorized
    Transfer-Encoding: chunked\r\n
    Date: Fri, 09 Oct 2015 16:22:47 GMT\r\n
    Server: AmazonEC2\r\n
    \r\n
    [HTTP response 1/2]
    [Next request in frame: 8371]
    HTTP chunked response
        Data chunk (254 octets)
            Chunk size: 254 octets
            Data (254 bytes)

In data field i can read:

"AWS was not able to validate provided access credentials" Is my signing process incorrect?
