Hi, is this peer0 or peer1?
did you run the ./bootstrap.sh script when you started the network? Then peer0 should automatically join the channel.If you did not run the script, check your starterFiles ==> config folder, see if the allarewelcome.tx file is there. If it is not, then the channel has not been created yet.
You can also check the orderer log by typing docker logs --details ordererID

Thank you. made it through Lab 3.. and guess what another error. lol i'll read through the other threads to see if someone else had this error.

@etrelz In case you are still facing this issue, this is how i solved it.
1. Ran startup.sh, so that recreated the channel allarewelcome (and deleted all the existing peer containers)
2. For both the peer definitions in docker-compose.yml file, i changed image: hyperledger/fabric-peer to image: hyperledger/fabric-peer:1.4.4
After starting the peer containers, i was able to fetch the genesis block for allarewelcome channel, as also able to join it.
Hope that helps!2 -
@manjushaawasthi
it was a good advice, still in my case did not resolve it.
After logging into the peer1, the command:
peer channel fetch oldest allarewelcome.block -c allarewelcome --orderer orderer.example.com:7050gets me an error:

Error: can't read the block: &{NOT_FOUND}Hi @LasToronto ,
Please go into the orderer container and check its log, maybe there is an connection error.Also, please check that the channel allarewelcome is actually up and running. You can see that in the orderer log as well.
If both connection is fine & channel running, there migth be an issue with peer1 authorization. Please type 'printenv' inside peer1 container, and check that all environment variables are set correctly.
I hope this helps. If not, let me know!

Error: can't read the block: &{NOT_FOUND}Also, @LasToronto , seems like you are inside the CLI container when you try the fetch command. You should do this from the Peer1 container. Hope that helps.

@Niklaskkkk
I issued the command from the Peer1.0 -
@Niklaskkkk what does it make you think that I am in the CLI container?

I issued the command from the Peer1.Hi @LasToronto , did you make it work? If not, what did the orderer log tell you? Also, check the Peer1 container log & please post both logs here, I will try to help you.
Maybe also try to reset your network first, by doing:
./teardown.sh
./bootstrap.shLet me know how it goes.

Spent a lot of time on this. Ultimately, the resolution was in the post above by manjushaawasthi, which was to change the peer image to HLF 1.4.4

I faced same issue, it happens whenever we clean the network, I resolve this issue by
go to Peer0 and create channel again
$ peer channel create -o orderer.example.com:7050 -c allarewelcome -f /etc/hyperledger/configtx/allarewelcome.tx
$ peer0.org1.example.com peer channel join -b allarewelcome.blockgo to Peer1 and join the channel
$ peer channel fetch oldest allarewelcome.block -c allarewelcome --orderer orderer.example.com:7050
$ peer channel join -b allarewelcome.blockThis works from rather than running bootstrap.sh every time.

@moolkothari I followed the same, created the channel again, fetch and join channel in peer0 and for peer1 - fetch genesis block and join channel.

Great suggestion @moolkothari . you can also adjust these commands inside the startup script. I did this during the tutorials, so basically the only command I had to run was startup, to restart the network (but remember to comment out generation of new keys etc since it is just demo netowork)
