That matters when you connect from a different machine. So let's focus on how you connect from Visual Studio? Can you include a screenshot. There is some puzzling information in your post. I assume that your machine name is CEO-PC and not CEO-PC/SQLSERVER? When you connect to a named instance, you should use a backslash (\) as the separator, not a forward slash.

Follow the below steps to see if you can resolve the issue. Step 1Make sure you are able to ping the physical server where SQL Server is installed from the client machine. If not, you can try to connect to the SQL Server using an IP Address (for default instance) or IP Address\Instance Name for a named instance. If it resolves using an IP address, you can add the SQL Server machine into /etc/host file. To add the entry in the /host file type %SystemRoot%\system32\drivers\etc\ in the run window and open the host file using Notepad.
