Connecting to kobo to excel Expression.Error

I was trying to connect kobo database to excel following the Get Data (command) from Web in excel. Initially it was working just fine. But then I had to made some changes to certain questions of the form, where I have changed one group name label and also changed the label of a question under that group. Now when ever I try to connect the database to excel, an error pops up stating that :
“[Expression.Error} The Column ‘Question Label’ of the table wasn’t found.”
Then the download fails. What should I do? Can any one please suggest?

Thanks in advance

Welcome to the community, @okup_mis! The best and easy approach is to re-do the connection again (i.e. configure the API settings again).
