stratum+tcp://eu.multipool.us:3333
That's the why the wrong pool or more port setting
use 3334, I don't see a them using a 3333 port setting looking at there stratum ports ..
you want
stratum+tcp://eu.multipool.us:3334
for LTC .
and I would use whatever miner works best for you in minera i have found BFG does for me so i use it .
what coin are you tiring to mine ? on multipool .
its looks like you nicehash connection is working right .
i just switch to 3334
