I have two DIY farms, farm1 has one node and farm2 has four nodes. After a power outage I noticed none of my nodes are working. They boot the OS and shortly after they connect the screen turns black with a blinking cursor.
Using the threefold connect app I upgraded my farms to V3 and downloaded the v3 OS from bootstrap.grid.tf. Now one node from 1stfarm and 1stfarm01 says it is connected from within the OS but I do not see my node online on https://explorer.threefold.io/all. I did wipe the disks and reboot all of the nodes.
Also I have three additional nodes with 1stfarm01 and when it boots up the OS says “node is not registered”
