Why won’t my Nikon D3400 take a photo with the 70-300mm lens in autofocus?

My Nikon D3400 works normally with the 18-55mm kit lens, but with my 70-300mm lens the camera focuses and confirms autofocus, yet pressing the shutter all the way does not take a picture. If I switch the lens/camera to manual focus, it will shoot. This did not happen before. Is there a setting that could prevent the shutter from firing when using autofocus?

According to the manual, shutter-release is disabled because:
- Memory card is locked, full, or not inserted (P 13, 292).
- Release locked is selected for Slot empty release lock (P 226) and no memory card is inserted (P 13).
- Built-in flash is charging (P 38).
- Camera is not in focus (P 35).
- The attached lens is not type E or G and the camera is not in mode M (P 253).
Camera not in focus, as @WayneF suggested, sounds quite likely.

Most likely the camera is preventing shutter release because it believes focus has not been achieved. On the D3400, the shutter can be disabled in autofocus if the subject is not in focus, even if the lens appears to be trying to focus.
Other possible causes listed in the camera manual are:
- no memory card inserted
- memory card locked or full
- flash charging
- a lens compatibility/mode issue with a non-G or non-E lens outside M mode
Since your other lens works, focus-related release lock is the most likely explanation. Try using a clear, contrasty subject in good light, and make sure the active focus point is on the subject. If it shoots in manual focus but not AF, that strongly points to the camera not accepting focus confirmation with that lens.
