Winsock2 - RECV not receiving in some context

[sami slim]

Context of my problem:
Using C++ ( on the client side ) I send a login with wrong parameter ( ON purpose ) and the server-side is sending me a logout message.
I am always able to send and receive correctly and the event is launched fine.
We have different scenario and parameters for the login: wrong username, wrong domain , wrong location .. The server always send a message for logout and disconnect the client.

Only in one case the RECV() is getting -1 ( when i send on purpose a wrong sequence of a message). While i can see the message using a network sniffer i was not able to receive this message. It always give me -1.

Can anyone help?

Below is the packets from the sniffer
