Zclassic appears to be breaking it as it is back up again.
What server location have you used?
Can you tell me exact server info and username?
I tested all three servers with Nicehash and Claymore but they are all working well now.
Orders are down again on Nicehash because it has switched to Zclassic. Server details are automatically taken from the API like I have on every other algorithm:
stratum+tcp://us-east1.hub.miningpoolhub.com:17023
stratum+tcp://europe1.hub.miningpoolhub.com:17023
aaronsace.nicehash_equihash:x
us-east1.hub.miningpoolhub.com
europe1.hub.miningpoolhub.com
These are not official servers. I will open them soon but not currently.
Please use below.
U.S. : us-east.equihash-hub.miningpoolhub.com:17023
Europe : europe.equihash-hub.miningpoolhub.com:17023
Asia : asia.equihash-hub.miningpoolhub.com:17023
These are dedicated servers for equihash (zec/zcl)
