Excel онлайн Javascript Плагин - вызов удаленного сервера err :: ERR_CERT_AUTHORITY_INVALID

Question

Я создал API отдыха в python следующий код:

app = Flask(__name__)


@app.route('/classifyCells', methods=['POST', 'OPTIONS'])
def index():

print(request.method)
print(request.data)

if request.method == 'OPTIONS':
    headers = {
        'Access-Control-Allow-Origin': '*',
        'Access-Control-Allow-Methods': 'POST, GET, OPTIONS',
        'Access-Control-Max-Age': 1000,
        'Access-Control-Allow-Headers': 'origin, x-csrftoken, content-type, accept',
    }
    return '', 200, headers

print(json.loads(request.data)['excel_file_path'])

data = requests.get("http://localhost:8080/FRITZ-WEBAPI/rest/getSmells/getSmells", data=json.loads(request.data)['excel_file_path'])
data = data.json()
print(len(data['cellSmells'].keys()))
print(len(data['cellComplexities'].keys()))
return data

#return "Hello from python."

if __name__ == '__main__':

    context = ('cert.pem', 'key.pem')
    app.run(host='0.0.0.0', debug=True, ssl_context=context)

Теперь мне нужно позвонить на этот сервер из онлайн-плагина Excel, javascript код плагина следующим образом:

Office.onReady(info => {
  if (info.host === Office.HostType.Excel) {
    document.getElementById("sideload-msg").style.display = "none";
    document.getElementById("app-body").style.display = "flex";
    document.getElementById("run").onclick = run;
  }
});

export async function run() {
    try {
        await Excel.run(async context => {



            var xmlhttp = new XMLHttpRequest();   // new HttpRequest instance
            var theUrl = "https://myPublicIp:5000/classifyCells";

            xmlhttp.open("POST", theUrl);

            xmlhttp.setRequestHeader('Access-Control-Allow-Headers', '*');
            xmlhttp.setRequestHeader('Access-Control-Allow-Origin', '*');
            xmlhttp.setRequestHeader("Content-Type", "application/json;charset=UTF-8");

            xmlhttp.onreadystatechange = function() {//Call a function when the state changes.
                if(xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                    console.log("Call successful.");
                }else{
                    console.log("Call unsuccessful.");
                }
            }
            xmlhttp.send(JSON.stringify({"excel_file_path":"/TU Graz - PhD/Metric-based-Fault-Prediction-for-Spreadsheets-master/datasets/raw/Enron Errors Corpus/1/2_HPLN0601.xls"}));


            //const range = context.workbook.getSelectedRange();
            var sheet = context.workbook.worksheets.getItem("TestSheet");

            const range = sheet.getRange("A1:E4");
            const conditionalFormat = range.conditionalFormats.add(
                Excel.ConditionalFormatType.custom
            );
            console.log(range)
            // if a cell has a higher value than the one to its left, set that cell's font to green
            conditionalFormat.custom.rule.formula = '=IF(A1:E4<=15,TRUE)';
            conditionalFormat.custom.format.fill.color = "red";
            var rangeAddress = sheet.getUsedRange();
            rangeAddress.load("address");

            //rangeAddress.format.fill.color = "red";

            var rangeFormValues = sheet.getUsedRange();
            rangeFormValues.load("formulas");



            await context.sync();
            console.log(`The selected range address was ${rangeAddress.address}.`);
            console.log(JSON.stringify(rangeFormValues.formulas, null, 4));
            console.log(window.location.pathname);
            //location.replace('/localizedtaskpane.html')


        });
    } catch (error) {
    console.error(error);
    }
}

Мой манифест. xml плагина выглядит следующим образом, я добавил IP своего сервера в AppDomain:

Каждый раз, когда я звоню через Интернет Excel после загрузки файла xml в Excel, я получаю ошибку net :: ERR_CERT_AUTHORITY_INVALID в консоли. Дайте мне знать, что я делаю не так.
