@MiningPoolHub

Please can you check that these algorithms are following the NiceHash stratum protocol to ensure compatibility with Excavator miner:
Equihash - NiceHash and Zpool works but MiningPoolHub does not
Lyra2re2 - NiceHash and Zpool works but MiningPoolHub does not
Ethash - NiceHash works but MiningPoolHub does not

Your Sia pool is also not compatible with anything but Claymore miners.
