Error "422" when using the New-UnityHostIPPort command

[bananaphonee]

I see the following error when I use the following command:

The array sends an error message:

Error code: 422
Error description: Unprocessable Entity
Error details: {"error":{"errorCode":5,"httpStatusCode":422,"messages":[{"en-US":"One or more speci
fied parameters are invalid. (Error Code:0x5)"}],"created":"2018-04-12T16:39:22.725Z"}}

Invoke-WebRequest : The remote server returned an error: (422) Unprocessable Entity.
At line:33 char:15

I do the following commands:
#Connection towards the server
$IP = Read-Host "Give the IP of the server"
Connect-Unity -Server $IP
#Creating a new Host
New-UnityHost -Name "Test2"
Get-UnityHost
#Creating a new Host IP Port
New-UnityHostIPPort "Host_7" -address 172.16.254.72 -netmask 255.255.255.0

I already have tried with "" and with '' at the -address and -netmask

I can connect to the server becaus when I create the Host I can look it up, the following is what I get when I do the Get-UnityHost.
Get-UnityHost
Id Name OsType Type

---

Host_7 Test2 HostManual

But when I do the last command then the I get the dialog screen if I am sure I want to create the Host IP Port, however when I click yes I get the "422" error.

Here is the output when I run it with -verbose:

Hello @bananaphonee

Thanks for opening an issue.

I'm not sure about this one because the documentation is not very explicit but, apparently, you can't provide a mask when you're adding an network address to a host. Mask are allowed only when you are creating a subnet...

Could you try by yourself ?

Hello @equelin

Thanks for the respons, I will try this next monday I can only access the server at the local place for security reasons.

I will let you know what the output is, and if it works then.

Hello @equelin
I have tested it like this:
New-UnityHostIPPort "Host_7" -address 172.16.254.72

And it works, thanks for the help
