My friends reported the same with cgminer. Is there any problem on scrypt stratum ?
cgminer does not work, try sgminer :-)
True, cgminer 3.7.2 has a bug and doesn't work with our stratum (Due to the NiceHash's latest state-of-the art engine, older miners are not supported.) ... please read
https://www.nicehash.com/index.jsp?p=faq#faqs0 ... you'll find detailed information on which miners are supported (basically all except of cgminer 3.7.2

). You'll also find some useful information on how to configure your miners, how to squeeze some more hashrate by using optimized kernels, etc.
