I just received four D3s from Bitmain in the Nov 1-15 batch (the 19.3 GH/s version). One of the four miners set up just fine, just like my September batch miners. I am having some of the same chip temp issues that other posters are having with this 19.3 GH/s miner, but at least it is mining.

The other three miners I received in this batch are giving me the following error, and I cannot seem to resolve it:

"Hardware Version: Socket connect failed: Connection refused"

I realize that miners will display this as they start up, sometimes for many minutes. But once configuration is complete and I click "Save & Apply," this message usually goes away and the miner connects to my pool as we would expect. This is not happening with the three of my four miners in the Nov 1-15 batch. These miners display the "Socket Connection Failed" message, and when I toggle with the settings in the miner browser to troubleshoot it, I'll get a browser "can't reach this page" error once I try to save and apply the settings (as if the miners disconnected themselves from the internet -- they are no longer discoverable on the network). A few moments later, the miners will spin up again (as if they restarted on their own) and I'll be able to reach their IP address in a web browser like normal, but they have the same "Socket Connection Failed" error message, and the same issues I had before (e.g., the browser saying "can't reach this page" once I try to save changes to settings) persist. This repeats over and over, and the miner never connects.

Does anyone have any idea what this might be, and what I might be able to do to troubleshoot it? I've opened a ticket on Bitmain's support site, but they are taking days to respond, so I figured I would check here to see if anyone here has experienced and resolved this on their own.

Here are the things I've tried:
1. Swapping ethernet cables
2. I've tested the miners on two different internet connections -- the internet connection that all my miners are on, and my back-up internet connection
3. Flashing firmware
4. Using the "reset" function
5. The tactic suggested in this thread (https://enforum.bitmain.com/bbs/topics/3876) that someone used to resolve a similar issue with the S9

Thanks in advance for any suggestions!

u got a bad controller, u can swap the working unit controller to this... check if that resolve your issue.

Thanks for the tip -- I'll give this a shot.
