Getting the following exception when tried to startup fabric gateway application client.

org.hyperledger.fabric.sdk.exception.ProposalException: getConfigBlock for channel mychannel failed with peer fabric-dev-peer1-org1. Status FAILURE, details: channel 'mychannel' not found*

Client was able to connect fine. But after restarting peer containers, application client failed to connect. Below is the error. However, I can see mychannel.block in peer1 at this location /tmp/org1/peer1/configtx I see this files at the above folder - channel.tx, mychannel.block, peerUpdate.tx

And with regards to certs of this peer, I have them on persistant volume, hence don't think I need to register the peer after restart as it would use the old ones.

Below is the error trace and it fails while executing this code val network: Network = gateway.getNetwork(channelName)
