Garage Door opener: everything but open/close since change

Have had the garage door controller for years. This weekend I changed out my opener. Installed a new Chamberlain B2401. Same maker as my 20+ y.o. previous model. But this one has built-in wifi.

Transferred my Wyze camera and garage door controller over to the new opener. Since transfer, have all functionality except opening & closing. Have camera image, have the chime & light flash when attempting to close the door, but nothing happens. I’m wondering: could this be anything other than the wires from the controller are not making good contact with the new opener?
