Hello friends, I am new to the group and to the world of mining and I write waiting for help, I have 2 avalon 841 miners connected in series, suddenly they stopped working and I see that the auc3 converter does not indicate any connection led, only the led that is on and the machines when turned on remain in a waiting cycle with the back light in green. Is it possible that the auc3 converter has been damaged or should I check the machines?

Thank you very much in advance for the help you can give me!!
