Operational Error connecting to SQL Server through Python3.7

I am using Python 3.7 and for a few years I have had a Python script that connected to an SQL server with the below code:

con_string = 'DRIVER={SQL Server};SERVER='+ server +';DATABASE=' + database
cnxn = pyodbc.connect(con_string)
cursor = cnxn.cursor()

Recently when running the script I get the below error:

OperationalError: ('08001', '[08001] [Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]SSL Security error (18) (SQLDriverConnect); [08001] [Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]ConnectionOpen (SECCreateCredentials()). (1)')

I am not quite sure how to interpret this and have tried looking for solutions but had trouble understanding much of it?

Thanks

Update 18 August 2020

With Gords help I have updated my drivers and built a new connection string based on the answer below:

Pyodbc error Data source name not found and no default driver specified paradox

con_string = 'DRIVER={ODBC Driver 17 for SQL Server};TrustServerCertificate=No;Network=DBMSSOCN;DATABASE='+database+';WSID=L13-CHRISTOPHER;APP={Microsoft® Windows® Operating System};Trusted_Connection=Yes;SERVER='+server+';'

But I am still getting the error

OperationalError: ('08001', '[08001] [Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]SSL Security error (18) (SQLDriverConnect); [08001] [Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]ConnectionOpen (SECCreateCredentials()). (1)')

Thanks

Method-1:- Check this out:

con_string = pyodbc.connect(driver='{SQL Server}', host=server, database=db1, trusted_connection=tcon) cursor = cnxn.cursor()

If Method-1 doesn't work for you then maybe your SQL Server drivers require TLS 1.0 which would be disabled on your computer. Changing to the newest version of SNAC will fix the problem for you

con_string = pyodbc.connect(driver='{SQL Server Native Client 11.0}', host=server, database=db1, trusted_connection=tcon)
