Good evening. I'm also trying to get a coin to work, the same problem arises, I think it's temporary difficulties. I wish everyone success.
Guys, does anybody staking the coins?
Do you know the time for the coins to mature?
My wallet is open, but "staking status" still shows "false".
"Enable staking" button doesn't help 
It seems, that the wallet has to be encrypted.
You can check the status with: getstakingstatus
