Try new version download from github, it seems works but pool for devfee not always ethermine.
what do you mean mining solo mode on ethermine?
Nothing special. I meant I dont mine 2nd coin, but it should not matter. My bat for example is : nodevfee.exe EthDcrMiner64.exe -epool eu2.ethermine.org:4444 -ewal 0xcb4effdeb46479caa0fef5f5e3569e4852f753a2.worker1 -epsw x -r 1
Try experimental version it is meant to fix pool switch problem, but I cant really test, cause havent noticed mine switch pools.
You should see NoDevFee: connect -> message in console if connection is being redirected.
I try experimental version, I see this in my console :
DevFee:ETH Stratum-connecting to 'eth-eu.dwarfpool.com' (87.98.182.61) port 8008
NoDevfee:connect ->asia1.ethermine.org:4444
NoDevFee:eth_submitLogin->0xxxxxxx
DevFee:ETH Stratum-connected (eth-eu.dwarfpool.com:8008)
ETH:Authorized
DevFee: start mining
DevFee: ETH 11/02/17-16:43:11 - New job from eth-eu.dwarfpool.com:8008
ETH: 11/02/17-16:43:11 - New job from asia1.ethermine.org:4444
ETH - Total Speed.................
DevFee: ETH 11/02/17-16:43:21 - New job from eth-eu.dwarfpool.com:8008
ETH: 11/02/17-16:43:21 - New job from asia1.ethermine.org:4444
