Answer 1

The message says it all - "Failed to connect to the configuration database."

You can click on the PSCDiagnostics log file to get more insights related to this error.

Check the account which you are using to connect to SQL Server instance, make sure it has the required permissions/roles to create configuration database -

1. Dbcreator

2. SysAdmin

3. SecurityAdmin

Once the correct permissions are set, re-run the Product Configuration Wizard and it should complete without any issues.
