SQL Serverへの接続中にFreeTDSエラーが発生しました。

Question

4.2から7.2までのすべてのバージョンを試しましたが、試したすべてのバージョンが無効です。

エラーログを確認し、Choosing TDS protocolに基づいて、SQL Server 2014がサポートされていますか？

概要エラー。

Error 20017 (severity 9): 
    Unexpected EOF from the server 
    OS error 115, "Operation now in progress" 
Error 20002 (severity 9): 
    Adaptive Server connection failed 

がTSQLでダンプされたログを見て：私は、SQLサーバはTDSが HTTP/1.1 likeヘッダーを返す必要があることをそれはよく分からない
