Hey, Pls share the error messages you saw on Horizon. As to your question: “Is there any way to create flat network on StarlingX openstack platform?” Yes, you can refer to CMD: $ openstack help providernet create $ openstack help network create Of course, since you had error on Horizon, there should be something wrong. So, let’s figure out why it failed first.

I installed StarlingX on a server, and now I'm trying to create "flat network" for public. However I couldn't find the way to make the network. I found "managed_flat", "managed_vlan", and "managed_vxlan" options in '/etc/neutron/plugins/ml2/ml2_conf.ini' file. When I install some OpenStack platform, I usually used devstack, and with devstack I could choose 'flat' option. Is there any way to create flat network on StarlingX openstack platform? And also network creation keeps failing on horizon dashboard. I had to use OpenStack CLI. Is it also a bug? Thanks in advance for any help!
