Hi Larry, Looks to me like your network configuration isn't consistent - your enp2s0 interface is still NetworkManager controlled, whilst the bridge isn't:
Mar 07 10:05:07 localhost.localdomain NetworkManager[4025]: <info> [1551924307.4967] ifcfg-rh: Ignoring connection /etc/sysconfig/network-scripts/ifcfg-cloudbr0 (d4b789ba-7321-548d-dabd-5c4150da0266,"System cloudbr0") due to NM_CONTROLLED=no. . . .
