I had the same thing happen in a VM. My interface was ens192, and this 
worked:

# ==== %< ====
# get status of all network devices
nmcli device status

# look at all the settings for ens192
nmcli connection show ens192

# enable ens192 at boot time
nmcli connection modify ens192 connection.autoconnect yes

# start ens192 immediately
nmcli connection up ens192
# ===== %< ====

Hope that helps.
