Eithernet failure

I have been running a umbrel node on a raspberry pi4 4gb with a 2tb ssd, for about 3 months with out any issues but yesterday found that the raspberry pi was on but there was no eithernet activity or ssd activity, was not able to find my node on my network Is it possible to resolve this issue or setup Wifi to start the node back , or will I have to start over from scratch and build a new node, your help would be greatly appreciated , Tony

I had a similar issue after returning from vacation. I power cycled the Pi, and all was happy. It had some days of synching to do to catch up, but all has been well since. Give it a try, unless you like days of syncing.
