Can you share the screen shot of the main control panel page immediately after you log in to your S9?
Thank you!
Antminer S9 does not work at
stratum+tcp://sha256.eu.nicehash.com:3334

The reason is not the S9 speed
Even my double S7 working at speed 9,5THs ,
S9 do not use Cgminer 4.8.0 Instead is BMminer Version 1.0.0
Apparently, this is the problem.
When Bitmain fix this error ?
Arghhh, this must be some state-of-the-art new-kind-of mining software where Bitmain obviously did try to reinvent the wheel instead of using the working solution (aka cgminer). We'll contact Bitmain and ask them to check what kind of bugs did they introduce in Antiner S9 "BMminer" and will ask them to fix the bugs and make it compatible with NiceHash system. Thank you very much for the feedback!
