"Session verification failed" while try to exchange token with Yahoo OAuth

Question

I use Yahoo OAuth 2.0 in my website. Everything's OK in localhost tests but when I use this login on my server, I got "Session verification failed" error while try to exchange the token. I use a trik to login from my localhost with client id, secret id and redirect uri of server app and it's worked. So I don't know what's going on in server.

Exchange token parameters:

URL: https://api.login.yahoo.com/oauth2/get_token
Method: POST
Header:
        User-Agent: *
        Content-Type: application/x-www-form-urlencoded
        Host: api.login.yahoo.com
        Content-Length: *
Request body:
        client_id=My_id&client_secret=My_secret&redirect_uri=My_uri&grant_type=authorization_code&code=TheCode
