Sharepoint Infopath Form GetUserProfileByName Connection Error

I have a form that try to get the user profile data using  a web service
suddenly the form stopped working with this type of error when trying to retrieve the data:

An error occurred accessing a data source.
An entry has been added to the Windows event log of the server.
Log ID:5566

this error only occur for a user , other user dosn't have this error , I tried to finc solutions on the web , but all of them didn't work

only one user have this error , I tried to give him full control over the site , but still the same , I think it is a permission problem.

any help will be appreciated.

I created a new Web Application and it worked fine with me , the other user is able to get the right infomation , but it is difficult for me to move to the new Web Application , so I think the problem is related to Web Application Configurations ,
