hello kevin ,

Log shows it is not able to  get br-ex interface , did you created this
interface , as we need to create this interface manually by runnig this
command

sudo ovs-vsctl add-br br-ex
$ sudo ovs-vsctl add-port br-ex <external interface>

Please verify this interface using ovs-vsctl show , it would show like this

Bridge br-ex
        Port "eth2"(in my case this is the external interface)
            Interface "eth2"
        Port "qg-e2df07f2-81"
            Interface "qg-e2df07f2-81"
                type: internal
        Port "qg-0ed547e2-8f"
            Interface "qg-0ed547e2-8f"
                type: internal
        Port br-ex
            Interface br-ex
                type: internal
