I just made a mistake and posted that we went live, but that was in fact the dev fee connecting and mining on my rig, hmf. Apologies to anyone who saw that, I deleted it very quickly after noticing.
The failure to connect on suprnova is universal. Pool is showing 0 workers and 0.00 MH/s for those ITT with this issue.
As no one is able to connect its likely that were just waiting for the main pool to go live quite soon, so Im leaving my rigs on, retrying to connect at the default of 20s. I was mining on testnet with the same settings as now so theres no issue with settings. Suprnova pool operator is also advising people to test their rigs on the ZEC pool now which also increases probability that we are simply waiting for the main pool to go live.
