docker exec cli peer channel create | failed to create new connection: context deadline exceeded | amazon managed blockchain

Question

I am trying to setup hyperledger fabric blockchain network using amazon managed blockchain following this guide. In the step 6, to create the channel I have executed the following command,

docker exec cli peer channel create -c hrschannel -f /opt/home/hrschannel.pb -o orderer.n-zzzz.managedblockchain.us-east-1.amazonaws.com:30001 --cafile /opt/home/managedblockchain-tls-chain.pem --tls

But I am getting the following error,

Error: failed to create deliver client: orderer client failed to connect to orderer.n-zzzz.managedblockchain.us-east-1.amazonaws.com:30001: failed to create new connection: context deadline exceeded

Help me to fix this issue.

Edited: I asked the same question in reddit. One user replied that he added listenAddress environment variable in my configtx.yaml file. He did not say clear information about which listenAddress and where to add that address in configtx.yaml. Here is my configtx.yaml file.

Answer 1

One must check if the peer container is able to communicate with the orderer container. curl orderer.endpoint port can be used to check the connection. If the peer is unable to communicate then either the orderer container is down or could be due to different security groups.

Update: As OP mentioned in the comments, changing the port helped in resolving the issue. One must give it a try.
