SharePoint2010 InfoPath on PageLoad getting 401 Unauthorized error after restoring with Produciton DB on DEV environment

The SharePoint system is In-place upgraded on Prod environment from 2007-->2010 from there we are trying to take backup and restore on Other environments(DEV/TEST) with the same setup. Only the In path in SharePoint is giving below error when try to create a new list, actually On Page Load there are couple of User information is been retrieved where we were receiving a warning alert "An error occurred querying a data source" and with the error details:

System.Net.WebException: The remote server returned an error: (401)
Unauthorized.
at System.Net.HttpWebRequest.GetResponse()
at
Microsoft.Office.InfoPath.Server.SolutionLifetime.DataAdapterSharepointListQuery.SendSoapRequestAndReturnResultSync(DataAdapter
adapter, WebRequest request)

Interestingly,InfoPath Preview is working as expected without any issues only it is failing when we open in SharePoint(All Published InfoPath). Web services are accessible and retrieving data when we access in Browser or outside of InfoPath. We have tried adding DisableLoopbackCheck in registry but no luck. Any help on this would be great!
