Autofocus has stopped working - hopefully an easy one

[DavidA]

Hi Guys

I am new to the photography.

I have a Canon 800D

The autofocusing was working with no issues so when in the viewfindered I half clicked and there would be the squares with the focused area that the camera has chosen.

I have manually overriden this by selecting the focus override button at the top and moving this around however, since I ahve done this I cannot get the autofocusing back.

The lense is set to RF BTW 

Any help would be appreciated.

Have you tried AF in both the optical viewfinder and in LiveView?

Found the issue. The auto AF selection was set to manual. changed to aut AF and I have the auto focus back.
