Tried, same problem.
It was already on the correct subnet with .99.99 because the subnet mask is 255.255.0.0, not 255.255.255.0.

Maybe the Pi can only accept class C IP, or can't use router as DNS?
Very strange, because the Antminer S1 works perfectly fine with any 172.31.x.x IP address...

I have a problem when using the RPi as mining controller. No matter which firmware or mining hardware I use, I get the same problem - no accepted shares, and 100% discarded work.

I tried the BTC Garden AM-V1 miner with the RPi that came with it. Everything was set up correctly, and I can log onto the RPi through web browser and SSH. My pool/worker information was also correct, but it would not submit any shares at all.

On the web interface, it can get work, but discards everything, and shows lots of hardware errors (over 10k in a couple of minutes).



Using the cgminer software directly through SSH, it keeps showing "Error submitting nonce" or something like that.
Here is the summery after stopping cgminer:

[2014-06-23 08:41:05] ********** chip 0 **********
[2014-06-23 08:41:05] total works: 16

[2014-06-23 08:41:05] total hibernate time: 30s
(Every other chip was the same, so omitted.)

I also get the exact same problem when mining Scrypt coins with the Zen Controller (RPi with Zenminer firmware) - everything is discarded.


Here are my network settings for the RPi and router:

RPi:
IP - 172.31.99.99
SM - 255.255.0.0
Gateway - 172.31.1.1 (router IP)
DNS - 172.31.1.1

Router (Zyxel Q1000Z):
IP - 172.31.1.1
SM - 255.255.0.0
DNS - Default (assigned by ISP)
DHCP is in the range of 172.31.0.1 to 172.31.0.255, so no conflict.
(I tried 2 different routers, same problem, so router is not the cause.)


It seems that the miner can get work, but can't submit it, hence discarded. I don't know if it's a basic network/setting problem, or something else more complicated. Anyway, this has been pure frustration for me...
Any help would be appreciated!

Thanks in advance.

So, what's going on with this coin?

I would be glad to put a few MH/s into it, if it doesn't turn out to be a waste of time.
However, as how things look at the moment, there are just no exchanges or buyers for this coin. I tried Comkort, put a million FCK there at 1 µLTC, no buyers in over 2 weeks...

What do you do with the files downloaded?
None of them will run in Win7...

Is this coin broken?

My wallet can't synch past block 340309.

OK, thanks for that.
I'll replace the nodes and see what happens.

I downloaded the new wallet client, but the database is still stuck at block 777855.

Should I delete the old database files and let it re-synchronize from scratch?

Yes, that helped. Thanks a lot!

It seems like you can't solo mine with an encrypted and locked wallet.

I've been having trouble solo mining this coin since a couple of days ago. The wallet synchs fine, except for the "checkpoint too old" message, but my cgminer seems to be unable to submit any found blocks before it turns stale.

It kept saying "Pool 0 communication failure, caching submissions". Then it says the share became stale while retrying, so I couldn't actually receive any of the blocks I found.

I am using the latest wallet client, and this only started happening about 2 or 3 days ago. I'm sure there is nothing wrong with my local network, because I can solo mine everything else fine.

Any ideas?

TIA.
