Can someone post his conf file while mining in Dwarf? There is some authentication issue and is not accepting the format of -u like "exchange-wallet.payment-id.worker" like it's suggested in Dwarf.
"pools":
[
{
"url": "stratum+tcp://xmr-eu.dwarfpool.com:9500",
"user": "exchange-wallet.payment-id",
"pass": "x"
}
]
or with worker:
"user": "exchange-wallet.payment-id.worker",
