I am trying to connect to my database on MS SQL Server 2016 using pyodbc via the below python script from my laptop (on Windows 10) and planning to have the code deployed in a Linux RHEL 6.4 server.
conn=pyodbc.connect('Driver={SQL Server};'
'Server=DB_Instance;'
'Database=DB_Name;'
'UID=user_name;'
'PWD=password;'
'Trusted_Connection=no;');
At my laptop, SQL Server (version: 10.00.17763.01) and SQL Server Native Client 11.0 (version: 2011.110.7493.04) are already available.
While executing the python script from my laptop, I am getting the below error message.
pyodbc.operationalError: (‘08001’, ‘[08001] [Microsoft] [ODBC SQL Server Driver][DBNETLIB]SSL Security error (18) (SQLDriverConnect); [08001] [Microsoft] [ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (SECDoClientHandshake()). (772)’)
As per the organization standard, TLS 1.0 is disabled on the windows server where the SQL Server is installed in the network. Since I am accessing the database via python script, we cannot temporarily enable TLS 1.0. I am looking for a direction. Any help is greatly appreciated!!

Gord Thompson pointed Guna in the right direction in the comments:
Can you try using ODBC Driver 17 for SQL Server and see if that works for you?
– Gord Thompson
Guna said that this worked:
I was facing different set of errors. While adding the port number in addition to the server name, the problem got resolved. The ODBC Driver name also needs to be updated. conn=pyodbc.connect(‘Driver={ODBC Driver 17 for SQL Server};’ ‘Server=DB_Instance,port;’ ‘Database=DB_Name;’ ‘UID=user_name;’ ‘PWD=password;’ ‘Trusted_Connection=no;’);

PROBLEM: —
When trying to perform password change for MSSQL server, you get the following error message:-SSL Security error
SOLUTION: —
It’s likely an issue with the version of the SQL Native Client driver being used to establish the connection.
-
Please Download & install «ODBC Driver 13 for SQL Server» on the CPM servers.
https://www.microsoft.com/en-us/download/confirmation.aspx?id=50420
Download 32 bit driver : x86msodbcsql.msi -
Install as usual
-
Edit MSSQL Platforms to change the connection command from
Driver={SQL Server};Server=%ADDRESS%;Database=%DATABASE%;Uid=%USER%;Pwd=%LOGONPASSWORD%;
to
Driver={ODBC Driver 13 for SQL Server};Server=%ADDRESS%;Database=%DATABASE%;Uid=%USER%;Pwd=%LOGONPASSWORD%; -
Restart the CPM service to pick up the platform changes & retest

Errors like SQL server connection failed SQLState 08001 can be really annoying.
The SQL server connection failed 08001 occurs when creating an ODBC connection on the Microsoft SQL.
At Bobcares, we often get requests from our customers regarding the SQL sever connection error as part of our Server Management Services.
Today, we’ll see the reasons for this SQL sever connection instance and how our Support Engineers fix it.
When the SQL Server Connection failed: SQLState 08001 Occurs?
Mostly the error SQLStateServer Connection failed 08001 occurs when creating an ODBC connection on Microsoft SQL.
We click Next on the SQL login screen. Then using the login information provided, the ODBC manager will try to connect to the SQL Server. But after some waiting time, it displays the below error message.
The main three reasons for the error SQL Server Connection failure are
- If we provide a wrong server name.
- If the SQL Server not configured to a network connection.
- The other possibility of this instance if we provide an incorrect login name or password.
How to fix SQLState 08001 Error?
Recently, one of our customers approached us with an error message ‘SQL Server Connection failed: SQLState 08001′.
Our Support Engineers log in to SQL Server Management Studio and make sure that the database name and other details are correct. In case, if the database server name is wrong then this error can occur.
Sometimes the message appears when we use ‘localhost’ as the Database Server name on the Database Settings screen in Confirm. But we can log in to the database in SQL Server Management Studio as a user, using the Server name ‘localhost’. Then our Support Engineers make any of the below two changes to fix the error.
- In the Database Settings screen, we change the Database Server name to the server name or
- In the SQL Server Configuration Manager, we enable the Named Pipes values in the Client Protocols.
Our Support Engineers follow any of the above two methods to fixes the error while creating an ODBC connection on Microsoft SQL.

I got same situation or error message and the issue in my particular case was that the number of connections was set to a maximum of 500. similar issue happened when this limit is reached therefore you can either reboot the SQL instance to get rid of idle connections. But if this happens frequently change the number of connections to unlimited (Value 0).

Hello Alemayehu,
Indeed the connection limit does cause SQL errors.
Named Pipes Solution solved.
Hi Manoj,
Glad to know that the problem got fixed.

Известные проблемы с драйвером ODBC в Linux и macOS
Скачать драйвер ODBC
Эта статья содержит список известных проблем в Microsoft ODBC Driver 13, 13.1, 17, 18 for SQL Server на платформах Linux и macOS. В ней также представлены шаги по устранению неполадок с подключением.
Известные проблемы
Дополнительные проблемы будут опубликованы в блоге о драйверах SQL Server.
Из-за ограничений системной библиотеки Alpine Linux поддерживает меньше кодировок символов и языковых стандартов. Например, недоступна кодировка en_US.UTF-8 . Дополнительные сведения см. в статье musl libc — functional differences from glibc (musl libc — функциональные отличия от glibc).
В Windows, Linux и macOS символы из кодировки области личных символов (PUA) или символов, определяемых конечными пользователями (EUDC), могут преобразовываться по-разному. Преобразования, выполняемые на сервере в Transact-SQL, используют библиотеку преобразований Windows. Преобразования в драйвере используют библиотеки функций преобразования Windows, Linux или macOS. Каждая из библиотек может давать разные результаты при выполнении преобразований. Дополнительные сведения см. в статье End-User-Defined and Private Use Area Characters (Символы, определяемые конечными пользователями, и символы области личных символов).
Если кодировка клиента — UTF-8, то диспетчер драйверов не всегда выполняет преобразование из UTF-8 в UTF-16 должным образом. При наличии в строке недопустимых символов UTF-8 сейчас происходит повреждение данных. Символы ASCII сопоставляются правильно. Диспетчер драйверов пытается выполнить такое преобразование при вызове SQLCHAR-версий интерфейса API ODBC (например, SQLDriverConnectA). Диспетчер драйверов не пытается выполнить такое преобразование при вызове SQLWCHAR-версий API ОDВC (например, SQLDriverConnectW).
Параметр ColumnSize функции SQLBindParameter указывает на число символов в типе SQL, а BufferLength — это число байтов в буфере приложения. Тем не менее, если используется тип данных SQL varchar(n) или char(n) , приложение связывает параметр как SQL_C_CHAR для типа C или SQL_C_VARCHAR для типа SQL, а клиент использует кодировку UTF-8, может появиться ошибка «Усечение данных строки справа» от драйвера, даже когда значение ColumnSize согласовано с размером типа данных на сервере. Эта ошибка возникает по той причине, что в результате преобразования между кодировками символов длина данных может измениться. Например, символ правого апострофа (U+2019) кодируется в CP-1252 как один байт 0x92, а в UTF-8 — как трехбайтовая последовательность 0xe2 0x80 0x99.
Например, если используется кодировка UTF-8 и вы указали значение 1 для BufferLength и ColumnSize выходного параметра в функции SQLBindParameter, а затем пытаетесь получить предыдущий символ, хранящийся в столбце char(1) на сервере (в кодировке CP-1252), то драйвер попытается преобразовать его в трехбайтовую кодировку UTF-8, однако результат не поместится в однобайтовый буфер. Значение ColumnSize сравнивается с BufferLength в SQLBindParameter перед выполнением преобразования между разными кодовыми страницами в клиенте и на сервере. Поскольку ColumnSize для 1 меньше, чем BufferLength , например, для 3, драйвер выдает ошибку. Чтобы избежать этой ошибки, убедитесь в том, что после преобразования данные поместятся в указанный буфер или столбец. Обратите внимание на то, что для типа varchar(n) значение ColumnSize не может превышать 8000.
Устранение неполадок с подключением
Если установить подключение к SQL Server с помощью драйвера ODBC не удается, следующие сведения помогут вам определить проблему.
Чаще всего проблема подключения связана с наличием двух установленных копий диспетчера драйверов UnixODBC. Выполните поиск libodbc*.so* в /usr. Если отображается более одной версии файла, (возможно) установлено несколько диспетчеров драйверов. Приложение может использовать неправильную версию.
Включите журнал соединений, добавив в файл /etc/odbcinst.ini раздел со следующими элементами:
Если возникает другой сбой подключения и файл журнала отсутствует, возможно, на компьютере имеются две копии диспетчера драйверов. В противном случае должны выводиться примерно следующие данные журнала:
Если для кодировки символов ASCII используется не UTF-8, например:
В этом случае установлено больше одного диспетчера драйверов и приложение использует неверный либо сборка диспетчера драйверов была выполнена некорректно.
При использовании драйверов версии до 17.8 у некоторых пользователей macOS возникает следующая ошибка:
(Эта ошибка была устранена в версии драйвера 17.9 и выше.)
Эта ошибка может возникать при установленной библиотеке OpenSSL 3.0. Обычно OpenSSL устанавливается с помощью Brew и содержит двоичные файлы openssl, openssl@1.1, и openssl@3.
Чтобы исправить эту ошибку, измените символическую ссылку двоичного файла openssl на openssl@1.1.

or «Data Source = Training or Ip; Database = db_name; uid = sdfa; pwd = dasfdf;»
4. User also has right to access that database.
I’m assuming you didn’t read the blog? You really should, it has some good general guidance.
1) Are you trying to connect remotely? If so, disable your temporarily firewall and see if this helps.
2) I’m not a connection string expert but go to www.connectionstring.com and use one of theirs. This will help ensure it’s not a connection string issue.
3) No SPs installed? You might want to try installing those.
