There is something to learn from automation specialists when it comes to troubleshooting.
If all else fails, do a hard reset (shutdown), unplug, wait and restart the system.
If that doesn’t work, then troubleshooting can continue.
If it works, then keep going.
When everything is going south and you have tried all you know, and seem to be making no progress, maybe it is wise to do a hard reset, unplug, wait and restart the system. Sleep is a great reset and unplug button.
