While running ./byfn.sh up from this tutorial https://hyperledger-fabric.readthedocs.io/en/latest/build_network.html i received errors. Therefore, i deleted all docker images as mentioned in that tutorial in the troubleshooting section by using the below commands.
docker rm -f $(docker ps -aq) docker rmi -f $(docker images -q)
After that, when i run the ./byfn.sh generate and ./byfn.sh up commands i got the below error.
Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).
