OperationalError: ('HYT00', '[HYT00] [Microsoft][ODBC Driver 17 for SQL Server]Login timeout expired (0) (SQLDriverConnect)')

Question

Hi,

I am encountering an issue while trying to connect to an SQL database using a Python script in my Jupyter notebook. The connection attempt results in the following error message: OperationalError: ('HYT00', '[HYT00] [Microsoft][ODBC Driver 17 for SQL Server]Login timeout expired (0) (SQLDriverConnect)').

Here is a snippet of the Python code I am using:

from azureml.core import Datastore

from azureml.core import Workspace

import pyodbc

datastore = Datastore.get(Workspace.from_config(), datastore_name='sql_datastore')

SERVER= datastore.server_name

DATABASE = datastore.database_name

USERNAME = datastore.username

PASSWORD = datastore.password

connectionString = f'DRIVER={{ODBC Driver 17 for SQL Server}};SERVER={SERVER};DATABASE={DATABASE};UID={USERNAME};PWD={PASSWORD}'

print(datastore.password)

print(datastore.server_name)

print(datastore.database_name)

print(datastore.username)

with pyodbc.connect(connectionString) as conn:

    cursor = conn.cursor()

    cursor.execute(f"INSERT INTO 'dbo.SampleData' ('Name', 'Age') VALUES ('TuNT', '26')")

    conn.commit()  
```I have verified that the server, database, username, and password are correct. However, I am still unable to establish a connection.  
  
Anyone know how to resolve this error  
  
Many thanks!
