F16v3 found not responding

[wilkija]

Any ideas on what would cause an f16v3 to hang up/stop responding.  I guess my mega tree stopped working sometime last night, but I didn't notice the message in fpp about being unable to reach the controller until today.  I cycled power on the controller and it came right back and started right back up with no issues.

Glad it was an easy fix, but it's early December and I'm sure it'll happen again.

F16v3 hard wired Ethernet to a switch that has my fpp on a pi3 B, and some other controllers.  Everything else was working fine.  Power is supplied by an off brand 12v ps through diyledexpress.  Also..I have the expansion board with ribbon cable attached.
