The zcoin pool is not very usable at the moment. Only getting this message on certain rigs for some reason. Nothing I could do to solve it. On other rigs I am not getting this error message at all.

Zcoin had serious problem on its network.
Zcoin dev had worked on this bug and I believe it's fixed now.
Hello,
Some of my rigs cannot connect to the pool for several hours. All rigs have same network

It looks like the problem is in the your stratum. When miner connect to the pool:
{"id": 1, "method": "mining.subscribe", "params": ["ccminer/0.0.2-djm34"]}
the miner gets this response:
{"id":1,"result":[[["mining.set_difficulty","VALUE"],["mining.notify","VALUE"]],null,4],"error":null}
and
null (result[1], ExtraNonce1) in the response makes miner crush
