If you're mining at Ipominer and haven't set the direct port for mining SC you should. Multiport changed to Pig again.
Scrypt direct port for SC at Ipominer: stratum+tcp://pool.ipominer.com:3443
P.S. Does anyone came across another pool mining SC with a bigger hashrate? Sorry for the repetitive question 

P.S.2 : Ok I give up, don't know what they're doing, it's already on SC again, the multiport.
