Hey guys, another newbie here. I've configured claymore with nanopool's auto generating tool. For Etherium I opened a wallet on myetherwallet and it works fine but I am having trouble with Siacoins. This is my program view http://i.imgur.com/EkecRfW.png, siacoin shares get stuck quite often (to the point where Current Calculated Hashrate and worker on nanopool stat page goes to 0/offline). Is it a server issue?
