Canon T6i Auto focus works on Live view but stops auto focusing on view finder

I’m sure I got a setting wrong or something. So I have AI servo active. When I open the live view the camera automatically auto focuses as I move it around from object to object. But when I close the live view screen and look through the view finder nothing happens. I can press the back button focus button or half press the shutter button to reach focus but it does not try to focus on other objects after that initial focus.
