SAP CPI Connectivity issue OAuth 2.0 with Salesforce REST API using a Rojo Adapter

[NikhilChary1]

We're trying to connect to Salesforce from SAP CPI using salesforce sender adapter in QA environment, but we're getting the below error from Salesforce and iflow is not getting deployed. All the IP whitelisting and everything is done from Salesforce side. We have tried doing a workaround by maintaining the Salesforce dev credentials in SAP CPI QA environment and iflow got deployed but using the Salesforce QA credentials we're not able to deploy the iflow. Please suggest can anything be done from SAP CPI side to rectify/fix the issue. We're using BasicAuthentication and Oauth Credential name and Secure token Alias for authentication.

Enable username password flow from salesforce then it should deploy.
