remote starting

[atom]

2017 gmc sierra 1500 with a factory remote start issue:   Up until this morning the remote starter had always worked as designed.  Today when the start is pushed on the factory fob the lights flash once and no start.   i tried my other fob with the same result.  i tried my.gmc app with the same result.  There or no lights/warnings on the instrumentation cluster on, of course the truck is in park, i opened and closed the hood hoping some safety feature there might be a bit wonky, i researched to see if there was a valet mode or something that i may have accidentally initiated but found nothing about that.  Of course the dealership was zero help kind of playing it off likes a novel event.  Do you have any ideas before i have to bring the truck in?

Try disconnecting the battery leave it off and push the horn a few times to discharge any voltage then reconnect. May not work but it’s worth a shot.
