To be sure the backend is up and running (not still starting up)
consider the following, probably without the echos:


for TRIES in $(seq $ATTEMPTS); do
     curl --silent --max-time 1 $BACKEND:6544/Myth/GetHostName > /dev/null
     if [ $? = 0 ]; then
         echo "$BACKEND is up"
     echo "Waiting for $BACKEND..."
