Error: NMP timeout

Hi guys,

I’m just getting started with nrf9160 feather and trying to “Load via Bootloader” and I’m getting an error:

 0 B / 68.17 KiB [-----------------------------------------------------------------------------------------------------------------------------------------------]   
0.00%Error: NMP timeout

My connection setup is something like this:
nrf9160 -> USB type C -> USB type A -> Adaptor -> Computer

➜ newtmgr conn show
Connection profiles: 
  serial1: type=serial, connstring='/dev/tty.SLAB_USBtoUART'
  vscode-zephyr-tools: type=serial, connstring='dev=/dev/tty.SPACE,baud=1000000'
