I have met the same error during run sample, it failed to connect. I fixed it with following steps:

get machine IP address with: ifconfig
replace localhosts in query.js with IP in #1

Example:

@@ -12,7 +12,7 @@ var options = {
     user_id: 'PeerAdmin',
     channel_id: 'mychannel',
     chaincode_id: 'fabcar',
-    network_url: 'grpc://localhost:7051',
+    network_url: 'grpc://****:7051',
};

What's your npm version? I use the latest version 5.1.0 – Angela Jul 07 '17 at 08:25
Angela's on the right path... you don't have fabcar, do you have all the pre-reqs?... you don't have dev-peer0.org1.example.com-fabcar-1.0. I'm using npm 3.10.10 – Mark P Jul 07 '17 at 19:09
my npm version is 5.1.0. But still getting the error – Subhankar Jul 08 '17 at 04:16
I'm also facing this problem after changing this – Tina Lee Jul 11 '17 at 07:36
I'm not sure what happened, but it works as expected when I redownload everything. – Tina Lee Jul 11 '17 at 15:37

Addition to Angela's answer:

To anyone having this issue and using Docker Toolbox, do docker-machine ls and copy the IP adress at the URL column of your ACTIVE machine and paste the IP adress to every localhost in both query.js and invoke.js files.

Wait for upto 90 seconds, it will work. For me after 90 seconds i got chaincode installation failed. I started again it worked. [Screenshot] (https://imgur.com/a/DbO708o) – abdul rashid Jun 05 '18 at 07:36

I have seen that error occur when datasources.json specifies that the network addresses start with grpcs://, but the network is not set up to use TLS. Try changing them to start with grpc://.

Do docker-machine ls

Output:

$ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOC default virtualbox Running tcp://192.168.99.100:2376 v17

copy the ip address mentioned , like : 192.168.99.100
go to \fabric-samples\fabcar\query.js
replace the localhost with the IP address
