I am running the May 2019 firmware on a ubuntu 18.04 machine for my set up over the last year with no issues until recently.
I am noticing that on viabtc and slushpool i am getting more rejected than accepted shares. Cgminer reports "(Too low difficulty)" when I do not have a difficulty setting in place.
CGMiner is showing Diff:13.9T in all 6 terminal windows.
What should the difficulty be per Terminus R606?
I also have 11 NewPACs on 2 Gekko Hubs connected to the same machine giving the same difficulty message.
