it is misconfiguration
network 192.168.111.0/22 could not be due to it is included in 192.168.108.0/22

Network: 192.168.108.0/22 (Class C)
Netmask: 255.255.252.0 = 22
Wildcard: 0.0.3.255
Broadcast: 192.168.111.255
HostMin: 192.168.108.1
HostMax: 192.168.111.254

First time Neutron fixes by itself but during next redeploy we are trying to set again 192.168.111.0/22 -- it fails
