Hyperledger Fabric failed to send proposal to peers Unable to resolve host peer0 org1

Question

While compiling the app, peers status is down. I tried to restart the docker container in order to change the peers status but no luck. Can someone tell me how to solve this problem?

Answer 1

This peer address does not exist on the internet

peer0Address: grpcs://peer0.org1.digitalberry-infra:7051

So you should change it to localhost. And also replace grpcs with grpc:

peer0Address: grpc://localhost:7051

This should work.
