The other miner are the same Avalon 1246 85th.
I have just check the network configuration and all look great.
I have also change the worker name with one of my friend and the problem still the same.
The only difference between the four asic is the firmware. The asic who not working have a different firmware of the three other since I have change the control board
This is pretty crummy i had to buy from 3rd party because they dont sell the boards or atleast not at the time. if this company isnt a scam i dont know what is. all this problem with firmware and miner ID garbage for what? to track for what? canaans tracking cost me 1000s of dollars and over a year of hashing.
