a few hours back pool shows that rig went offline but the miner still submit shares.
i've restarted the miner and still submit shares as usual but pool still doesn't show that.
been in touch with ethermine support but they insist that it wasn't a server side fault.
still not sure if it was a pool or miner issue but till then, i'll continue using claymore.
Had the same issue connected to the asia1.ethermine.org. Looks like the difficulty had been raised on that pool too?
Switched to the us server for now and its reporting as normal.
Be good to know if you hear anything back!
