Antminer D3 pool issues

[griffoncoin]

Hi,

I have 2 D3 Antminer having issue with mining pools,  The pool status goes down after like 12 hours, Any idea what can be the cause . 

So far i have tried

x11.mine.zpool.ca:3533
stratum-us.granatgas-pool.info
stratum-eu.granatgas-pool.info

I have a D3 that is showing "dead" status on any pool I connect to, but will only get an "Alive" status for Ant-pool. I do not want to be stuck with only antpool. Any notion that this is a bug or a backdoor enabled by Bitmain?

shoot. I am finding out the same thing. I'm not earning anything on antpool either so it is a lose lose lose situation.
