I'm getting all my shares rejected (Ethereum) since 12hs ago....

What's your address?

Inspecting the logs I see several miners that keep mining even though stratum authorization failed (the pool communicated that to the miners). The only possible reason for this is currently a malformed wallet address. Could you post yours just to make sure that you are not among those rejected miners?

I have an issue as well. Wallet 0xfF684104992bd26B6326bcA4620D733526c0Ddb1

Which miner is that?

Ethminer - https://github.com/ethereum-mining/ethminer

Hello!

This is my address:

0x7326e6F2bC2E9280E731700537A847585b6d2F35

I'm using Claymore 10.0 in SimpleminingOS (Ubuntu).  I will try again to see what's going on now.

Thanks!

Same thing, I get all my shares rejected:

These are the parameters I have for Claymore 10.0:

-wd 1 -r 1 -epool stratum+tcp://eth.poolmining.org:3072 -ewal 0x$walletETH.$rigName -epsw x -esm 3 -allpools 1 -mport -3333 -asm 1 -mode 1 -ftime 10 -allcoins 1 -ttli 80 -ejobtimeout 5

Haven't touch anything, it was working like a charm until yesterday night....

Thanks!

Working on it.

OK!  One more thing, in Simplemining OS, the wallet address goes without the "0x" in the begining (you define it in a variable named $walletETH), that's why I have to add it manually before the -ewal parameter.

As long as its submitted using the 0x prefix all should be fine.

Fixed using https://github.com/coinfoundry/miningcore/commit/4c54c313844c69e84591c544510527fdd27313d6

Update deployed. Not seeing rejects anymore.

Thanks! Now its working fine again :)

Confirmed all good now.
