I was able to resolve it.
Modify the Connected app in Salesforce: (Edit Policies)

・Relax IP restrictions
・Permitted Users to "All users may self-authorize"

Invalid Grant error means password that you pass is incorrect. Adddtionally the comments below by Luwei will also help 
Also you need to enable the API access for the Profile Set in Salesforce 
Below settings need to be adjusted in the connected app which needs to be created to access the Salesforce API .
