why if I specify in epools.txt us1.ethermine.org it says that it requires login.worker and cant be used as devfee pool.
but it dosent need LOGIN, the format is -ewal . so you can use it as devfee. So why reject?
Make sure you use "0x" in the beginning of your ETH address.
If it still does not work, I need to see config.txt and epools.txt completely.
