I have setup my Nano in headless mode and connected it to the jupyter notebook, and after turning off Jetson and then back on again, it does not allow me to connect through ssh nor does the display output work anymore. I have reflashed an SD card and still it will not load a display. The green LED does come on as well. I have not been able to find a previous topic related that addresses my current ongoing issue. I have 2 Jetson Nano 4GB devices for which both are having the same issue. Any direction or help would be greatly appreciated.
