fails on all pools I tried - any hints?

[aleqx]

I just installed this according to instructions on a Ubuntu 16.04.2 with all updates to date. I tried flypool, nanopool, suprnova using the EWBF miner ... all fail. Connecting directly to the pools works just fine.

my config.json is

{
        "wallet": "${MY_ZCASH_ADDRESS}.proxy",
        "pool": {
                "host": "eu1-zcash.flypool.org",
                "port": 3333
        }
}

Launched the proxy ... seems to work so far:

# node proxy.js
zecProxy is listening on port 8000
zecProxy connected to eu1-zcash.flypool.org:3333

Then I launched the ewbf miner ... it fails:

# ./miner --server localhost --port 8000 --user ${MY_ZCASH_ADDRESS}.rig1 --pass x --solver 0

Executing the miner directly works just fine:

... now if I execute it again I get:

undefined:1

Did the pool ban me? Hmm

On nanopool with nodejs 4.2.6 I get this:

Looking at the code, I have to ask: have you actually used this successfully with multiple miners behind the proxy? The reason I'm asking is that your code sends the same job to all miners for all broadcast jobs from the pool (the mining.notify method) ... isn't that going to create duplicate work for the miners?

Hi guys, We have same issue (first post) with eu1-zcash.flypool.org Any hint ?

[deke997]

I have the same issue as the first post with EWBF. nhqminer works fine.

Any ideas?
