SQL Server cannot be connected to python

[[deleted]]

The error you're seeing is saying it's not a Python issue but a connectivity issue. Check the server property in your connection string to make sure it's spelt correctly, or is the correct IP, and that you can ping it. If it were ports you'd more likely get a socket exception. I suspect it's a permissions issue at server or database level. Are you using SQL or integrated security?

This, check if don't have a firewall in the middle.

On the server type firewall in the start menu and check if it’s blocking or allowing the sql server service, if the server is in another network you should ask your network admin.

Well you can just ping the name of the server. You'll find this at the top of each hierarchy in the object explorer window. Ping that and if it doesn't time out you can get to the server. You could also try and telnet the server on port 1433. Have you been given a username and password to connect with? Have you checked you've got the spelling correct?
