Ubuntu MAAS ERROR:network Node has no address family in common with the server

when deploy a node with the OS, an error occured. The people said  it’s a software issue. Actually it is the fact. Error:Node failed to be deployed, because of the following error: {“network”: [“Node has no address family in common with the server”]} Ok I figured this out. Under Subnets tab, click the fabri1 tab ,if  enable DHCP function ,it will reserved the ip .It may make some conflict after running a long time,and report an error. I deleted the reserved range 192.168.190.255/24 – 192.168.200.252/24 that was automatically assigned by MAAS. I don’t really need it anyway. I then had to go into the Machines tab for the node I was having problems deploying. Then I clicked on the Interfaces tab. Then edit the interface that was connected by clicking the three lines under the actions tab at the end of the interface tabs and choose edit interface. Make sure the Subnet is assigned to the subnet you are deploying on. Make sure the IP mode is set to auto assign.
