Hello guys, I know this is not the best place to post this problem, but as I know you are the best and smartest guys over here please help me with this if you are able:
I've been mining in kano since six months I think and from yesterday I realized my TH/S dropped a lot and I went to check my miners and I found this:
I have an Antminer S9 and it got in the chain #8 GH/S(RT) = 0.00000
I've seen in the forum some problems about that and says it is a board problem.
My antminer is out of warranty, and I am not able to send back to bitmain to get a repair ticket because it is almost impossible to send it from my country. So please help me guys Sad I'm really worry about that Sad
Here is a picture of what I'm telling you:

You need to post a screenshot of the full page for seeing all chips. but it looks like you have a problem with 1 hashing board; should send to bitmain for repair or purchase a hashing board and replace it at your own risk.
I also highly recommend to have a 2nd and 3rd mining address for backup (not just the 1st one).
It's possible with Awesomeminer to put backup ?
Because i manage pool with it not directly by web interface.
EDIt:
Just add the pool on the pool page for each miner

You confirm is useful when the first is offline.
how can i check if i lost something because first was offline ? there is a stat which mean that ?
EDIT2:
I have some doubt if the profit is very good if a minimum luck is not here....
For example, with my hashrate 27.3TH/s, i earn an average of 0.0046 by block found. (it's the stable earning after 3 days of running)
If i estimate with expected block for september, i found :
31 * 0.0046 = 0.1426
On nicehash, for the same Hashrate, i have 0.2597 for the month, minus 4% = 0.2493.
To have the same earning on Kano, it need 54 blocks found for the month.
Everything is calculated in BTC, and the BTC/USD exchange will not affect that.
My simulation is wrong ?
