I use Environ-wallet and it was synchronizing and staking until 10/11/2017 but now it shows "not staking because wallet is offline" and 0 active connections.
AppData/Roaming folder/Environ
create a notepad file rename Environ.conf (delete the .txt)
then put in
addnode=108.180.37.52:12723
addnode=74.113.32.12:12723
addnode=86.145.68.129:12723
and hopefully you will get the blocks coming in again if your ready to stake. Thanks
