pool difficulty too low on suchpool ........ can't connect
Use the high diff ports you'll have better luck. if you are nicehashing start with a smaller order and increase it, should fix your issue.
Single Asics, I'd say this is good up to 3-5 TH/s per worker:
stratum1.suchpool.pw:3323
stratum2.suchpool.pw:3323
Anything bigger AND anything nicehash should go here: (diff 1024-20048 target 2048)
stratum1.suchpool.pw:23323
stratum2.suchpool.pw:23323
