Answer 1

Typically, to troubleshoot this, you go to SQL Server Configuration Manager (SSCM) and:

1. ensure Shared Memory protocol is enabled
2. ensure Named Pipes protocol is enabled
3. ensure TCP/IP is enabled, and is ahead of the Named Pipes in the settings

Maybe it can help: Could not open a connection to SQL Server

Note : If this is a new instance of SQL Server be sure SQL Server and Windows Authentication is enabled

1. Right Click the Server in SSMS and pull up server properties
2. Go to Security–> Select ‘SQL Server and Windows Authentication Mode’
3. Restart the Server and Login with the credentials
