Hi Eswar,
As per your error log, database is refused to connect. my suggestion
1. Cross check the user credentials, which should be same as MSSQL DB login credentials in Data services (i.e. User name & passwrd Parameters)
2. And as per screenshot,
In the server URL you have mentioned localhost. better try with server IP address with port. And check from MSSQL side, Client protocols all are enabled.
Image may be NSFW.
Clik here to view.
