Ok so lets see.

What have you tried so far as to trouble shooting?

 Huh

Well also might be good to check your network setup.  Diasable your network adapter or reset it.  I had issues with mine when I relocated my machine.

For some reason it finds a new IP for the unit. Mine decided to add a number from XXX.XXX.X.105 to XXX.XXX.X.106.

We will work this out buddy. I tore hair out for 6 hours.

Hi guys,

You know what, I had a similar problem and I tried it all.

Reset button, power down for an hour, individual testing if hash boards. Did it all. When I contacted bitmain they just quoted the user manual. What a croc of shite!

Anyhow to cut this short I found my problem.

Disconnect all your power and hash cables.

Pull out your control board.

Flip it over and I found serious solder oxidisation.

My miner is in a controlled environment so no moisture or anything.

The oxidisation creates artificial paths between points which causes the machine to go WTF!!

To fix get a NEW very dry toothbrush and brush out any oxidisation.  Chuck your board back in and boot her up.

Mine ran like a dream.

Hope this helps guys.

Ill take a small BC OR BCC doni if your machine starts up.
