have they ever worked with that controller?

Have you ever had other  Avalon  gear working with that controller?

Can you find the controller in a browser?

so the mining window in your browser is visible?

and it shows 2 of the 4 a841 units.

it used to show all 4 a841 units?

are all four attached in 1 chain?

if a chain of 4

rasp pi - 841-841   -      841-841.


one chain.  are the two bolds ones dead?

that could mean the  wire with lots of space is bad
