I started one master node through AMAZON AWS and was working for two days (10 coins given)  then suddenly stopped. I am not able to figure out the problem and able to start again. I am trying through chaincoind masternode start command but not working and no message is coming. Now I have to give this comand as Start chaincoind "chaincoind --daemon to start again or any thing else. How I can also recover my wallet and chain coins at this stage when not working.
