You'll need to send it to a lens repair service. Do not attempt to disassemble the lens yourself; you'll only make the problem worse and may damage the lens beyond repair.

Clean the camera / lens contacts with a lint-free cloth

hi, clean the camera contacts also , change the firm ware of the lens , hope this helps

Check you have not switched camera t manual focus...if it's on auto then try changing various focal lengths to see if it kicks in....if it does intermittently you may have a cracked flex cable...this eventually happens with long throw lens because the cable gets weaken as it stretches and closes.It is also possible the ribbon became dislodged at the Circuit board just behind the mount.

Bad lens. But go to camera shop with lens just to confirm.

Use the settings that will give you the best exposure / shutter speed / focus

Try cleaning the lens and camera contacts gently with a lint-free cloth
