Prtractor Error with Gitlab CI/CD Pipeline

Question

We have a secured network and Protractor test suite runs locally. But when running the Gitlab CI/CD pipeline with headless chrome it returns network errors

This is my conf.js

exports.config = {
    framework : "jasmine2",

    multiCapabilities : [
        {
            browserName: "chrome",
            chromeOptions: {
                args: [
                    "--incognito", 
                    "--headless", 
                    "--no-sandbox", 
                    "--disable-gpu", 
                    "--window-size=1920,1080",
                    "--disable-dev-shm-usage",
                    "--allow-insecure-localhost"
                ],
            },            
        },
    ],

    specs: [
        './tests/sample.ts',
    ],

    seleniumServerJar: '../node_modules/protractor/node_modules/webdriver-manager/selenium/selenium-server-standalone-3.141.59.jar',

    seleniumAddress: 'http://localhost:4444/wd/hub',

    chromeDriver: './node_modules/protractor/node_modules/webdriver-manager/selenium/chromedriver_98.0.4758.102',

    directConnect: true,

    onPrepare: function(){
        void browser.manage().timeouts().implicitlyWait(10000);
        void browser.waitForAngularEnabled(false);

        require("ts-node").register({
            project: require("path").join(__dirname, "./tsconfig.json"),
        })
    },

    plugins: [{
        package: 'protractor-screenshoter-plugin',
        screenshotPath: './outputJS/reports/e2e',
        screenshotOnExpect: 'failure+success',
        takeScreenshots:'true',
        withLogs: 'true',
        writeReportFreq: 'asap',
        imageToAscii: 'none',
        clearFoldersBeforeTest: true
     }]
}

Error appears

I tried adding webDriverProxy and proxy. But same result appears.
