Hardhat with Ganache

I am trying to deploy my contracts on ganache but its giving error

Error in plugin @nomiclabs/hardhat-ganache: An error occurred in GanacheService: listen EADDRINUSE: address already in use 127.0.0.1:8545

Ganachec is running on 127.0.0.1:8545, but if i close ganache then it syas unknown network.

Can anyone guide me how to solve this ? Thanks :slight_smile:
