Error while consuming web-service: Connection refuse: connect

Hello,

While consuming web service which returns XML, I am getting below error:

Application log:

[context: com.thingworx.webservices.context.HttpExecutionContext@4d1285e][message: Execution error in service script [test2] :: Connect to www.holidaywebservice.com:80 [www.holidaywebservice.com/50.62.169.119] failed: Connection refused: connect]

Service Code:

var params1 = {
proxyScheme: undefined /* STRING */,
headers: undefined /* JSON */,
ignoreSSLErrors: undefined /* BOOLEAN */,
useNTLM: undefined /* BOOLEAN */,
workstation: undefined /* STRING */,
useProxy: undefined /* BOOLEAN */,

timeout: undefined /* NUMBER */,
proxyPort: undefined /* INTEGER */,
password: undefined /* STRING */,
domain: undefined /* STRING */,
username: undefined /* STRING */
};
// result: XML
var resultXML = Resources["ContentLoaderFunctions"].GetXML(params1);
var params2 = {
infoTableName : "InfoTable",
dataShapeName : "SOAP_DataShape"
};
// CreateInfoTableFromDataShape(infoTableName:STRING("InfoTable"), dataShapeName:STRING):INFOTABLE(StringDataShape)
var result1 = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params2);
for each (var tag in resultXML.*::HolidayCode) {
var newRow = new Object();
newRow.HolidayCode = tag.*::Code;
newRow.Description=tag.*::Description;
result1.AddRow(newRow);
}
result=result1;

I am using TWX 8.2.1, any suggestion?

Thanks!
