Enterprise Search Unauthorized Error

I’m receiving this error when I try to use enterprise search, I don’t receive errors in my deploy environment, Could someone guide me on what to check?

ESearch deploy

You do have this checked on your user account, correct?

Check the Epicor user running the Enterprise Search index. Right click on the index and Modify Search Index Settings. Click Previous until you get to the Epicor User. Validate that the user and password is correct.
