Unable to validate junodb installation on Ubuntu 22.04 using docker engine 24.0.6

[ambi88dex]

Upon starting the junoservices using docker/start.sh

I'm getting the following error while running the validation command docker exec -it junoclient bash -c 'nc -vz proxy 5080'

nc: getaddrinfo for host "proxy" port 5080: Temporary failure in name resolution)
