Hey, @Sudip,

First thing you need to start fabric. Run ./startFabric.sh in fabric-dev-servers because it seems like your fabric isn't running.

If you get any errors like some containers already exist then do a ./teardownFabric.sh first then run the start command again. This will give you a basic running network with one org, one peer, and one orderer.

Once your network is ready to run then you have to create your admin card by running ./createPeerAdminCard.sh. Once you reach this point then you are ready to install and start your chain code.

Another reason may be proxy issues, so you need to clear that in order to deploy successfully.
