Unable to connect to orderer #1

Open Shal10 opened 5 years ago

Shal10 commented 5 years ago

While running setupnetwork.sh, getting below error while creating channel:

Error: failed to create deliver client: orderer client failed to connect to orderer0.ordererorg1:7050: failed to create new connection: context deadline exceeded

Any help regarding this?

xmhubj commented 5 years ago

Which step of setupnetwork.sh this error was being observed? Usually this error indicates a certificate issue.

Shal10 commented 5 years ago

It is while "channel creation", the job goes in a loop and does not complete successfully. Log shows the error mentioned above.

Similar problem here. I am getting following error message:

UTC [grpc] Printf -> DEBU 004 grpc: addrConn.resetTransport failed to create client transport: connection error: desc = "transport: Error while dialing dial tcp 10.106.33.24:7050: getsockopt: connection refused"; Reconnecting to {orderer0.ordererorg1:7050 } Error: failed to create deliver client: orderer client failed to connect to orderer0.ordererorg1:7050: failed to create new connection: context deadline exceeded

Have you found the reason ?

I didn't run into this issue, but you can debug deeper to find it out:

  1. Make sure all the service/pod are up and running.
  2. Check the connection between orderer client and orderer0.ordererorg1
  3. Check the log message of the problem oderer, the specific cause would be seen there, certificate issue, etc

Hi, how can one do step 2? Thanks!

This was my orderer log after the error message:

peer channel create -o orderer.example.com:7050 -c allarewelcome -f /etc/hyperledger/configtx/allarewelcome.tx

Error: failed to create deliver client: orderer client failed to connect to orderer.example.com:7050: failed to create new connection: context deadline exceeded
