run the SDN express and load balancer is not configured correctly and showed failed

Did some testing and discovered that SDNexpress.ps1 fails in sections 3
write-SDNExpressLog "STAGE 3: Host Configuration"

foreach ($h in $ConfigData.hypervhosts) {

    Add-SDNExpressHost -ComputerName $h -RestName $ConfigData.RestName -HostPASubnetPrefix $ConfigData.PASubnet -NCHostCert $NCHostCert -Credential $Credential -VirtualSwitchName $ConfigData.SwitchName
}

in SDNexpressmodule i removed the | out-null to see more data on screen

I think that the load balancers are not working correctly since certificate has issue and new-networkcontroller is using as resource id SDNswitch ID and not the HCInode server ID

I'm receiving a similar issue, also at the exact same location, and my output is similar to yours. I ran -verbose to see the output, here it is.
