pyodbc 无法连接到 MSSQL

Question

我想使用 pyodbc 连接到 mssql 服务器，但不知何故我无法连接。

这是代码

import pyodbc 
server = '172.xx.xx.xx,1433' 
database = 'DATABASE_BI' 
username = 'COMPANY\test.xx' 
password = 'test123!@#' 
cnxn = pyodbc.connect('DRIVER={ODBC Driver 17 for SQL Server};SERVER='+server+';DATABASE='+database+';UID='+username+';PWD='+ password)
cursor = cnxn.cursor()

这是 output

OperationalError: ('08001', '[08001] [Microsoft][ODBC Driver 17 for SQL Server]TCP Provider: The
wait operation timed out.\r\n (258) (SQLDriverConnect); [08001] [Microsoft][ODBC Driver 17 for SQL
Server]Login timeout expired (0); [08001] [Microsoft][ODBC Driver 17 for SQL Server]A network
related or instance-specific error has occurred while establishing a connection to SQL Server.
Server is not found or not accessible. Check if instance name is correct and if SQL Server is
configured to allow remote connections. For more information see SQL Server Books Online. (258)')

我不知道是什么让它出错。 是不是因为mssql服务器拒绝了请求？
