Hyperledger Fabric: Error: error getting endorser client for channel: endorser client failed to connect to peer0.org1.example.com:7051: failed to create new connection: context deadline exceeded

Problem

I was following this Hyperledger Fabric tutorial: Building Your First Network

There’s a shell script called byfn.sh which stands for Build Your First Network.

I ran the following command which generates the required certificates and genesis block:

./byfn.sh generate

And then, ran this command which brings up the network with docker-compose up:

./byfn.sh up

While running the above command ./byfn.sh up, I got the following error:

Error: error getting endorser client for channel: endorser client failed to connect to peer0.org1.example.com:7051: failed to create new connection: context deadline exceeded
!!!!!!!!!!!!!!! After 5 attempts, peer0.org1 has failed to join channel ‘mychannel’ !!!!!!!!!!!!!!!!
========= ERROR !!! FAILED to execute End-2-End Scenario ===========

ERROR !!!! Test failed

Solution

Found different solutions over the internet.

1) Clear docker containers, images, and volumes

docker rm -f $(docker ps -aq) && docker rmi -f $(docker images | grep dev | awk '{print $3}') && docker volume prune

2) Clear the network (bring the network down) and re-run the up command

./byfn.sh down
./byfn.sh generate
./byfn.sh up

3) Re-install the platform-specific binaries and config files

Visit this tutorial: Install Samples, Binaries and Docker Images

As mentioned there:

• Open terminal
• Go to your fabric-samples directory
• Run the following command:

curl -sSL http://bit.ly/2ysbOFE | bash -s 1.2.0

This command will:

• Install the Hyperledger Fabric platform-specific binaries and config files for the version specified into the root of the fabric-samples repository

• Download the Hyperledger Fabric docker images for the version specified

4) Update docker and docker-compose to the latest version

This solution finally solved the error in my case.

In the Prerequisites page, it says that we need:

Docker version 17.06.2-ce or greater
Docker Compose version 1.14.0 or greater

I had:

docker version 18.x.x
docker-compose version 1.21.1

But, they were not the latest version.

Hence, I just gave a try to update the docker and docker-compose to the latest version.

And, then ran the byfn.sh shell script and everything went fine without any error.

./byfn.sh down
./byfn.sh generate
./byfn.sh up

Hope this helps. Thanks.
