Always ... ALWAYS post the full launch command line and the logs.

[papampi]

Sorry launch command added,
Thats all the log it gave, exits after that.

[AndreaLanfranchi]

Try removing password

./ethminer -P stratum+tcp://[email protected]:20535 -U --api-port -3333

[papampi]

Same error without password too

[AndreaLanfranchi]

Wonder if it ever worked with any release.
They seem to NOT implement proper response to mining.subscribe

>> {"id": 1, "jsonrpc":"2.0", "method":"mining.subscribe", "params":[]}
<< {"id":1,"result":[[["mining.set_difficulty","deadbeefcafebabe6929000000000000"],["mining.notify","deadbeefcafebabe6929000000000000"]],"6fffece5",4],"error":null}

They should reply with a "result": true"
They also miss "jsonrpc":"2.0" in json message which is mandatory,

Think I wont fix.

From their FAQ page:

Miner

(1) Claymore Dual Miner(by Claymore) "Recommend"
(2) Ethminer fork
(3) Qtminer (by Etherchain)
(4) Eth-stratum-mining-proxy (by Coinotron)
(5) Eth-proxy (by Dwarfpool)

Other miners are inefficient or not maintained anymore. (4),(5) are proxy programs that should be used with (2)program.

You should use eth-proxy to mine with ethminer on miningpoolhub.com

I think I was using miningpoolhub.com some time ago. But I'm ok with not supporting crappy stratum protocol implementations. deadbeefcafebabe6929000000000000?

[papampi]

I have been using MPH with all the previous ethminers and no problem
So how can I use it now?

[chfast]

@papampi Also 0.14.0rc5?

[AndreaLanfranchi]

Apparently mph is stuck at the "old" jsonrpc v1 ( http://www.jsonrpc.org/specification_v1 )
I have to assume that older version of EthStratumClient (which incorrectly assumed to be subscribed or authorized without any check) did allow the usage of ethminer with mph. But that implementation was quite unsafe.
