BFGMiner not working with Slushpool?

[jphelps]

I recently unearthed my old Block Erupters, u2, and u3 (questionable condition). So I downloaded BFGMiner, logged into Slushpool again, set up a .bat with the whole bfgminer -o xxxx:xxxx -u xxxx.xxxx -p xxxx.xxxx.

That closed out immediately after trying to start it. So I then tried the normal exe file for BFGMiner and it actually stayed open, however after putting in stratum+tcp://stratum.slushpool.com:3333 for the URL, my user, and a random password, I am greeted with:

Code:

pool 0 JSON stratum auth failed: ]
   -1
   -Internal Server Error,
   Null
]

I have no clue what this means or what im doing wrong. Its been quite some time since I mined last, I know that it wont really have much of an output, im mostly just doing it for fun at this point.

Anyone got any ideas? Sorry if this isnt the most detailed post, its 3am and im rusty.

I never mined with these so i can't help much. i thought maybe it was a pool minimum hashrate but couldn't find anything. They do have a whole list of other stratum addresses that are location specific, you could try a few of those just to see if it resolves the issue.

Side note you might just want to toss these on a solo pool as a lottery. I'm not even positive of what there are for options on the solo lottery there was CK pool, but it may not be running anymore. Kano pool had discussed launching one, but not being into the solo game myself I'm not positive. Good luck sorting out your issue.

I am rusty too, but at Slush you may need username.workername (I don't know how it handles missing worker). https://slushpool.com/help/bitcoin-setup/?c=btc
Since tell "Auth Failed" I'd go by this first (also log in and create a worker).

And you may also have surprises on low hashrate, but that may translate in more disconnection than useful hashes.

I'm not sure that your hash rate will do anything on SlushPool. I would recommend pointing the devices at https://solo.ckpool.org/ for lottery mining. Recently, I had 10 U1/2's (20+ Gh) running against the pool for about 2 months, but stopped after I never solved a block larger than 10 million.

I know that the VH fork for CG Miner runs the U1/2's fine, but not sure about Block Erupters as I do not have any.

Which OS are you running? Windows, Unix, Raspberry PI?

Auth failed usually means a mistake in the user(worker) name. It has to exactly match the login name you use in the web page.

The .machinename is optional, if you use it, it shows its pretty name in the dashboard. If you omit it, the hash rate shows in a generated "auto" miner. It really doesn't mind if you use it or not, and the password can even be blank or the classic x, doesn't matter.

Again: the username has to match exactly any caps used to login in the Slushpool web page.

Because of the minimal withdrawal amount, I'm not sure its such a good idea to use this old miner with Slushpool. You should really go with https://solo.ckpool.org

BTW: You don't manually create workers in Slush Pool, at least not in its current UI incarnation. the .machinename in the miner user(worker) name field will do that automatically for you.

Kano pool does have a solo mode, but, you have to make an account (old accounts don't work) and configure it for solo mining. Unlike ckpool, where you just use your bitcoin address as user(worker) name and mine without needing to set up a pool account. Also dust payments like what this machine could only make, might take ages (if ever) for getting out any satoshis, not sure if he ever implemented the non manual method of paying dust. Oh and if he feels like your asic is funny, it gets banned, so there is that. In addition, 4 blocks per year is already on the lost cause side of the equation, i think that pool will close sooner than later, a shame since i love pplns pools the most, but a low hashrate for pplns means game over, as we have seen here before.
