He does not work at

Hmm, to be honest we don't have any S9 to test so we can't tell for sure. But it would be highly unusual that it would not work. Can you please post a print-screen of the first page of Antimer tab System / Overview?
And can you please configure your Antminer S9 with a separate Bitcoin address
(so that only this miner would use this Bitcoin address) and leave it mining on NiceHash for approx. 15 minutes? Thanks.
i can confirm this and i don't recommend people trying it for themselves until there's some kind of fix.
Reason i say DONT try it is because in my case the chip temperature spiked a LOT
it has indeed to do with bmminer crap.
Antminer S9 is not working in Nicehash

Are you referring to NiceHash Miner or NiceHash service in general? NiceHash Miner does not support SHA256 ASICs (they can't do any other algorithms, so it doesn't make any sense to support them). But regular connection to NiceHash service (see
https://www.nicehash.com/index.jsp?p=software#sha256) should work. Does this work for you? If not, what is the actual issue?
Best regards,
NiceHash team.
Maybe adding a stratum proxy to your mining software will solve the problem with s9 by making shares run through it?
