i did changed the setting and enabled the connection and changed the port to 1433
like this picture

and this for ports

and i am sure that is the server name and password are correct
and i faced no errors in installation
but i still this connection error

i have edited folder in directory
C:\Windows\System32\drivers\etc
by adding this line
127.0.0.1 cadb.nflavor.com
although i tried without the line but still the same error
i have a router
if that is may cauze the problem
the whole information in the file etc is here :
