this can happen due to the peer leaving the channel or some error related to it.

try to list the peers that are in the channel and see if yours is there

peer channel list

If not add again

peer join channel -b <my-channel-name>.block

try removing the wallet and re-enrolling the admin and user. In the /fabcar/javascript directory:

rm -r ./wallet
node enrollAdmin.js
node registerUser.js
node query.js

If that doesn't work, you can try the instructions in: https://hyperledger-fabric.readthedocs.io/en/release-1.4/write_first_app.html and stop the network (in the /first-network directory):

./byfn.sh down 
docker rm -f $(docker ps -aq)
docker rmi -f $(docker images | grep fabcar | awk '{print $3}')
