Something not right in your config, your batch file says music @ epool.io and dcr @ supernova and your log says eth @ nanopool and pasc @ nanopool
Check config.txt, epool.txt and dpool.txt
Thanks for the reply Spitkicker. The Musicoin pool I mine from requires the use of an ETH miner (see here: https://gmc.epool.io/#/help) pointed where it is. The musicoins are mined fine and I can confirm them in my wallet. It's just the DCR that's a problem.
I pulled the batch info from config.txt as you suggested, filled in with current info, and ran it. Both music coin and DCR are coming up as authorized, eth (musicoin) shares are accepted just like before but still getting rejected DCR shares
What else could it be? I'm about to email Suprnova and say wtf mate.
