I'm trying to point my S9's at NiceHash for SHA256 mining. Unfortunately I'm seeing a large percentage of rejects (around 30%). Most of the rejects seem to be duplicate shares:
2016-11-07 08:26:41,291 INFO [Pool-NiceHash-Thread]:strat.mining.stratum.proxy.worker.StratumWorkerConnection - REJECTED share (diff: 32768.0) from [email protected] on NiceHash. Booo !!!!. Error: JsonRpcError [code_=22, message=Duplicate share., traceback=null]
2016-11-07 08:26:45,510 INFO [Pool-NiceHash-Thread]:strat.mining.stratum.proxy.worker.StratumWorkerConnection - REJECTED share (diff: 32768.0) from [email protected] on NiceHash. Booo !!!!. Error: JsonRpcError [code_=22, message=Duplicate share., traceback=null]
I tried to work around this by enabling and disabling extranonce and by setting a reasonable minimum difficulty. I also tried both syntaxes for specifying the extranonce to NiceHash (i.e. adding "#xnsub" and "/#xnsub" to the URL).
I've also tried a single worker behind the proxy, in case the issue is related to multiple workers.
Nothing I change seems to help.
When I point the S9s directly at NiceHash, they work fine with almost no rejects. But of course that defeats the purpose of a proxy.
Any recommendations for getting this proxy to work with NiceHash?
i have been using this proxy for a long time now with the nicehash system ...
i have not had any real issues - except for the idle disconnection issues which has been fixed ...
though the proxy works - it has never been tested with any asic miner ...
what is the s9 - scrypt? ... sha256d? ...
which port are you mining on? ... how long are you mining for? ... are these errors immediate or after sometime? ...
these are some of things i think will answer the issues ... at least i hope
