i have not.
just checked it out.

got the same error: Stratum authentication failed

here is my config
cpuminer-gw64-corei7 -a timetravel -o stratum+tcp://unify.acc-pool.pw:4211 -u test -p test

Does this mean that it goes trought but the user and password is wrong?

it should not be wrong but i just cant figure it out
