switch port for ipp printer - windows

Question

I need to change the port of an ipp printer using powershell or any other form of command/script
I tried to create and switch Port like this:
Add-PrinterPort -name "newport" --PrinterHostAddress "http://{the new ip}"
Set-Printer -name "myPrinterName" -PortName "newPort"
but the printer doesn't get the new printing jobs after this.
I checked and the old port and the new port are different,
the command Get-PrinterPort | select * shows this for the two port:

How can I create a new "internet port" ?
I checked all the docs,forums,etc.. I could but didn't find anything about it.
I know the "internet Port" is created automatically when i created my printer with this command: Add-Printer -Name "myPrinter" -DriverName "driverName" -PortName "http://{the ip for the printer}"
