 Error: proposal failed (err: rpc error: code = Unavailable desc = transport is closing)

 hyperledger Fabric v 1.3.0

 docker -v 2.0.0.0

 startFabric.sh file code is below

Hey, @Sagar,

Can you clarify a few things please:

  1. gRPC version. libprotoc is not gRPC version.
  2. Is the endpoint a gRPC server as well?
  3. Is there a proxy in between.

1 answer to this question.

Hi, @Sagar,

transport is closing" error is often caused by the server closing the connection. Try to look at the server-side logging and see if there's any transport error there.

 These errors are happening extremely early in the connection. You could try setting grpc.WithWaitForHandshake in your DialOptions and see if anything else shows up in the logs. My guess is the connection was never actually valid. Are you using TLS or WithInsecure?

It can be tricky to debug this because the error happens on the client-side but the root cause of the connection being closed is on the server-side. Turn on logging on both client and server, and see if there are any transport errors.

thanku soo much for your response

Hey, @Sagar,

Glad to help you with your query doubt. If you have a query on any technology do post it in the Edureka community, We will try our best.

i got this error after executed this cmd on gitbash 

curl -sSL http://bit.ly/2ysbOFE | bash -s 1.3.0

previously hyperledger fabric worked fine but due to docker reset all images of hyperledger fabric deleted and then i execute above cmd on gitbash ,after that i execute ./startFabric.sh file then out is following

Hi, @Malik,

Could you please confirm that you getting any kind of error while doing this?

yes i getting error

Error: proposal failed (err: rpc error: code = Unavailable desc = transport is c
losing)

Hi, @Malik,

"transport is closing" error is often caused by the server closing the connection. Try to look at the server-side logging and see if there's any transport error more there.

Could you please post the client-side logs and server-side logs? Because there might be errors are happening extremely early in the connection.
