无法使用 PyMySQL 建立与服务器的连接 [WinError 10054]

Question

对于 Python 和 SQL 来说都是新手，所以请原谅我的笨拙。我们在我的公司有一台服务器，我正试图通过一些 python 代码连接它。我有正确的 IP 地址和登录凭据，我可以在 SQL Server Management Studio 中毫无问题地连接到它，但我无法通过 PyCharm 的数据库功能或我的代码连接到它。如果有什么不同，我正在运行 python 3.6。

这是我正在运行的代码（为了安全起见，我省略了服务器 IP 地址和登录凭据）：

    import pymysql

    db = pymysql.connect(host='server ip', 
                         port=1433, 
                         user='username', 
                         passwd='password', 
                         db='Development DB')

    cursor = db.cursor()        
    cursor.execute("SELECT VERSION()")
    data = cursor.fetchone()
    print("Database version : %s" % data)
    db.close()

当我运行代码时，大约 2 分钟没有发生任何事情后，我收到此错误：

Traceback (most recent call last):
  File "C:\Program Files\Python35\lib\site-packages\pymysql\connections.py", line 1021, in _read_bytes
    data = self._rfile.read(num_bytes)
  File "C:\Program Files\Python35\lib\socket.py", line 575, in readinto
    return self._sock.recv_into(b)
ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:/Users/aubrey_s/PycharmProjects/Drawings_Converter/Drawings_Converter.py", line 5, in <module>
    db = pymysql.connect(host='ip address', port=1433, user='username', passwd='password', db='Development DB')

    packet_header = self._read_bytes(4)
  File "C:\Program Files\Python35\lib\site-packages\pymysql\connections.py", line 1029, in _read_bytes
    "Lost connection to MySQL server during query (%s)" % (e,))
pymysql.err.OperationalError: (2013, 'Lost connection to MySQL server during query ([WinError 10054] An existing connection was forcibly closed by the remote host)')

据我了解，似乎建立了连接，但服务器强制它在一段时间后关闭。谁能让我更深入地了解问题可能是什么？提前致谢！

正如我在another post 中所写，您可能想尝试使用pymssql，以防您的数据库不是 MySQL 数据库而是 Microsoft SQL 数据库。
