Error :

We are getting below Error while loading Infopath form in SharePoint 2010:

error connecting webservice infopatherror-1

Solution :

This has nothing to do with Infopath forms data connection or republish.

We have to make an entry in HOST file for each of WFE’s & adding site binding in the IIS web site for the web application having issue. This fixed the issue.
