protractor not stopping selenium server - selenium-webdriver

Question

We are getting a timeout error after our protractor tests have completed.
Error updating Sauce pass/fail status: 'Could not send request: connect ETIMEDOUT
We have tried adding these to the onComplete function in our conf.js:
browser.driver.quit(), browser.driver.stop(), and different forms like this. None seem to be stopping the web driver. for the stop() function we are obviously receiving the error that the function DNE. For the browser.driver.quit(), we are receiving the timeout still. How do we stop the webdriver?
My protractor version: Version 3.3.0
My Complete conf.js:
exports.config = {
sauceUser: process.env.SAUCE_USERNAME,
sauceKey: process.env.SAUCE_ACCESS_KEY,
tunnelIdentifier: process.env.SAUCE_TUNNELL_IDENTIFIER,
webDriverProxy: 'my-companies-proxy',
specs: ['e2e/*spec.js'],
framework: 'jasmine2',
onPrepare: function(){
var caps = browser.getCapabilities()
},
multiCapabilities: [{
browserName: 'chrome',
version: '41',
platform: 'Windows 7',
name: "chrome-tests",
shardTestFiles: true,
maxInstances: 25
}],
onComplete: function() {
var printSessionId = function(jobName){
browser.getSession().then(function(session) {
console.log('SauceOnDemandSessionID=' + session.getId() + ' job-name=' + jobName);
});
}
printSessionId("Protractor Tests");
browser.driver.quit();
}
}
