Washer and Dryer displaying "Couldn't add device" when adding to smartthings

Using wf45k6500av and dv45k6500ev with the HD2018GH adapter, which lists the washer and dryer as compatible models. I can go through the setup process no problem and get the Success! Washer or Dryer connected, add a device name and set as favorite. But once I finish the setup the device is displayed as unconnected and says “Couldn’t add device. Try again”
