Check if SQL instance is running...

Check the protocol that is specified in the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\Client\ConnectTo\DSQUERY
This value typically reflects the settings in the CNU, but sometimes it does not.

If the value is DBNETLIB, it uses one of the protocols in the enabled protocols list of the CNU. If a specific protocol is listed, that protocol is used instead.

Make sure you have also enabled access in the Windows Firewall.

Open the properties of Windows Firewall and add as exception the programs "sqlservr.exe" and "sqlbrowser.exe" that are in the installation folder of your SQL server.

I use the express version, and this solve the issue.
