Error: Connection Attempt Failed

Hi,
Thanks to this youtube, I have set up all the things somehow and started PoS mining yesterday. So, it was good. But this morning, it seems something wrong with it. Does anyone help me to solve the issue please?
I tried other command. It seems to be ./dcrctl --wallet getbalance is working (replied numbers), while ./dcrctl --wallet getstakeinfo replied nothing (told me "-1: Chain RPC is inactive).

I'm not very familiar with technology things, so I might be asking very stupid question though...

I'm using Mac Book Air, and the file I installed yesterday was "dcrinstall-darwin-amd64-v1.0.5".

Below messages are copied and pasted from Terminal.
MacBook-Air:decred mypc$ ./dcrwallet --walletpass ***** --promptpass

Oh you hit the point! Thank you for asking to my silly question. It worked!!
