Had this issue with1 rig after update and a restart fixed it. Have you tried cutting the power and waiting 5 mins? What do you see in the screen / shell?
The equipment returned to operation around 11 pm yesterday.
During these 24 hours off the air, the option was miner ETC. Because ETH was not going into any miner or pool.
Lo monitoreaste por monitor o shell? Si arranco a las 11, es que estuvo siempre prendido. Fijate que reporta el minero. Tambien proba cambiar de pool a ver que pasa, solo para testear
