This afternoon i have a strange log message :

Quote

[17:23:30] WARNING: POTENTIAL CLIENT.EXPLOIT!
[17:23:30] Reconnect requested from Pool 0 to stratum.nicehash.com:3333
[17:23:40] Waiting for work to be available from pools.

Any problem on the pool ?

I would rather prefer if payments (for providers) be made only once per day. With the current rates, having payments 4 times per day only produces dust (or near-dust) for 98% of the miners (that is, everyone apart from the top 15 miners with huge hashrates), and so we will all end up paying huge tx fees for using those btc in the future.

kenshirothefist, would changing that be something you could consider?

Thanks for all the rest of the good work!

Update to NiceHash sgminer and reconnects will not happen.

I'm mining at another pool and using nicehash as reserve pool, it's in settings of my main pool web page. Before everything worked fine and when my rig had no job at my main pool it was switching to nicehash. Now this option stopped working today and their web page shows warning:
"This pool (meaning nicepool) issued a client.reconnect which is incompatible with our service. In order to keep our system from getting banned by the remote pool (nicehash) we've temporarily disabled this connection"
I've got a question to support or developers how can I make it work like it was working all time before today (I'm using sgminer 4.1.153 from the start of nicehash).
Thank you.

when can we use cgminer with nicehash? my hosted miners at gawminers.com is showing 100% reject rate

Now that we've fixed GPU-based sgminer and cgminer compatibility (https://nicehash.com/software/) we'll focus on GridSeed as well as on other ASIC miners (A2 Miners, Zeus miners, Lunal Lander, KnC Titan, Alpha Viper, etc.). Source code is ready, we just have to patch some of the popular forks (like https://github.com/dtbartle/cgminer-gc3355). We'll also make sure that hosting providers will use mining software that is supported with NiceHash (we're in contact with hosting providers). Stay tuned.

Yea it looks like someone must have exploited the site as why would the price double there are other places cheaper. Has me a bit paranoid atm wondering wtf is going on.

Yesterday, or two days ago I observed a pattern. I don't know if it's an exploit, hack, or just someone stupid but it goes like this:

1) If the top order paid 5.00 (for example), someone create a new order of 6.00 (it was not exactly 1.00 more but it was definitly higher. As a buyer you would first try with 5.10, no?).

2) Wait for the order to become alive and miners start to work on it.

3) Cancel the order after few seconds only. (no, the order did not become dead before he cancel. So it's not someone who have trouble with his pool)

4) Repeat.

5) ? ? ? ?

6) Profit (sorry, I could not resist Wink

)

But seriously, I don't know what was going on and why someone would do that.... Undecided

hmm, interesting ....

Important note for all sellers - providers

After extensive internal testing we can finally provide you with our own sgminer and cgminer builds.

As you probably already know, NiceHash is using some advanced stratum protocol features, therefore older mining software is not supported. We have prepared optimized sgminer and cgminer builds for you to get optimum performance when mining with GPUs on NiceHash. Of course, these builds will also work equally optimal on other pools.

Our builds includes patch for seamless order swaping without interupts, the idle bugfix as well as some other minor impovements.

Get the software here: https://nicehash.com/software/

Please, download our sgminer or cgminer binaries and please report if it is working well for you. We will apprechiate any feedback!

On our software download page you will also find links to latest BFGMiner builds with good GridSeed support (BFGminer 3.99.0) - hopefully Hashra and others will include the latest BFGminer in their software builds as soon as possible.

Thank you for using NiceHash!

Please, when you are saying about rejects, state following: what kind of rejects are you getting (share above target, duplicate or stale), your mining software and location.

I'm using Hashra Mini Controlla 1.4.5 (latest) located in central USA. I have 10 miners each at 850 Mhz and currently am running at 48.09% rejection rate.

No, there is coin rush.

Many orders appear dead, because all of them are using pools:
- dedicatedpools which is apparently unstable
- trademybit which is dropping connection for every coin switch causing it to appear dead for next 2 minutes

Ha! Which coin rush is it? What is hot coin right now? Is it UVC?

Maybe. The profitability of UVC right now is 8.89.
And according to AltCoinCalendar.info there is no new coin launched today. That's why this sudden rush surprise me.

Yeah. Damn dedicated unstable pools. My last attempt to make profit of a new coin failed because unstable pool. Angry

Wow. What is the lastest cool Scrypt coin people mine??
Price of orders suddenly doubled. Shocked

EDIT:
Or it's actually some kind of attack? Most of the 8.00+ orders are dead...

How many miners are you using? If you have many, then some might be unable to connect due to stricter firewall rules.

Some people suggested using appropriate miner with appropriate config.

Only one, so that can't be it.

I'm using appropriate miner and a common config for my card that is giving me more hashrates from any other mining pool out there.

Fixed. Please be patient. We are experiencing heavy DDOS for few days now already.

Do the DDOS attacks have anything to do with lower hashrate when mining from here? I'm still getting 12% less hashrate than what I'm used to and no rejects.
I'm currently using sgminer 4.1.271 (the original binaries, not the modded from here). I'm from Montreal, Canada and I do submit stale shares.
