Thanks you so much for help guys, appreciate.
Indeed I found the solution, it was the temperature protection which was switching off the hash rate.

Hi fanatic 26

Thank you so much for help.
Indeed it works after I waited longer. I got a hardware version and BMiner version on the overview appearing and then some numbers on the miner status.
Unfortunately it seems like I'm facing some other troubles. 
The GH/S(RT) goes up to 14.000 for a few seconds then goes to 0.00 on three cards. Then the red fault light on the miner goes on. I tried on reset again once and every time waited around an hour.
Any idea of the problem?

thanks

Hello everyone,

I'm new in mining, I just got a new S9 two days ago from bitmain.

Unfortunately I cannot make the S9 working. I still got the message "Socket connect failed: Connection refused" on the system overview page. I also have nothing on BMIner version champ ( i guess it's normal if he cannot connect)

First I didn't have anything on the hardware version line, so I tried to upgrade the firmware, I also upgrade with the fix and then upgrade again. since then I have Socket connect failed: Connection refused

I tried with another network cable
I have a new APW3 psu from bitmain i don't think it would be the problem.
I tried a reset and also reboot.
I also tried like bit main suggests on their website to disconnect the mother board from the cards but the message socket connect failed was still there, so I don't think that one card could be faulty.


 
Anybody has any clue that could help me?
I wrote to bitmain, but I guess they need a few days to answer

Any suggestion would be welcome as I start to loose hope in mining. 
Thanks
