Hi, I recently switched from NH and had some questions about Zcoin pool mining using my GTX 1070 with the miner listed by MPH (cc-djm):

1. Which server address should be used and why are there differences? Lyra2z.miningpoolhub... or zcoin.miningpoolh...

2. On the Zcoin Dashboard, I can see the Recent Credits for the past few days.
On 2017-12-08 it was noticeably lower, at about 1020AM UTC, I stopped receiving shares. At about 1220PM I received the email "no shares from worker in 10min". I logged in via TV and it was running as expected. But the shares only resumed at about 0930PM UTC.

How can I debug this? My Monero miner was still going strong, so it cannot be the network connection.
