Just a heads up but Dwarfpool Expanse pool is seriously ill at the moment. Delayed payouts (17hrs) and now not recording shares correctly. It may be a front-end issue and recover but since there are no notices it's kind of hard to tell.....
Mining at
https://exp.suprnova.cc and never had any problem
If ocminer supported the Dwarfpool-style proxy for EXP I would be too. I like to be able to switch about easily.
It actually is supported at exp.suprnova.cc port 2222 but you'll need to patch your eth-proxy because on my pool you don't use wallet address as username.
So either you use my version from here:
https://github.com/ocminer/eth-proxyOr you simply comment out those lines:
https://github.com/Atrides/eth-proxy/blob/master/eth-proxy.py#L14-L16
