One of my R4's that stopped hashing on one board has stopped hashing completely after trying to restore the original firmware. The hardware version listed under system overview says " Socket connect failed: Connection refused".

I have tried powering off several times, reboots, updating firmware, etc. No more hashing. There has to be an easy fix to this without sending to Hong Kong or letting sit in Denver for weeks on end. Any thoughts?

EDIT: unplugged the original board that did not hash and fired back up, the one remaining board is hashing again at 4th/s!

I had similar issues with multiple S9 units of my clients - I am wondering if just some loose wires that can be fixed easily by someone with the necessary skill. Very interested to learn your experience.

I had the exact problem with an S9 unit 14Th
It is currently being serviced by bitmain and should return soon. One board brought down the whole machine and unplugging it fixed it
