How to enable Net.SOAP (SOAP) in PDF to work in Adobe Reader 2018 without MethodNotAllowed?

Hi, I creating PDF document with script on its load. Script content is some like:

try {

var cURL = "http://www.whitemesa.com/interop/InteropTestC.wsdl"

var cTestString = "This is my test string";

// Call the echoString SOAP method -- it is an RPC Encoded method

var response = SOAP.request(

{

cURL: cURL,

oRequest: {

"http://soapinterop.org/:echoString": {

inputString: cTestString

}

},

cAction: "http://soapinterop.org/"

});

app.alert('ret', 3);

} catch (expp) {

app.alert(expp, 3);

}

I know what it need some "Form Save Rights" to be viewable in Adobe Reader. And I saving it in Adobe Acrobat Pro with: File menu -> Save As other -> Reader Extended PDF -> Enable more tools.

But when I opening new pdf in Adobe Reader 2018.11.200400, I seeing "MethodNotAllowedError" again/

Question: what should/could I fix? My SOAP server will be my own, what I should install onto it? I just need an internet-datetime in my pdf.
