After starting 'node init.js' everything looks to be started up correctly, Stratum Pool Server started and coin network info is displayed, no problems until i try to connect with a miner:

seems this issue is with cryptonight only. all other algos have no problem with authentication. i am trying to use cryptonightv7... is there any additional info i need to put into coins json definition, like variant 1? i tried adding "cn_variant":1 but still have problems authenticating due to 'unknown stratum method'.
