Django Jenkins raises WebDriverException when processed to Selenium server

I start Selenium server hub by command

java -jar selenium-server-standalone-2.33.0.jar -role hub

and Selenium server node by command

java -jar selenium-server-standalone-2.33.0.jar -role node -hub http://localhost:4444/grid/register -browser browserName=htmlunit

Then i'm trying to execute code:

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
server =  'http://localhost:4444/wd/hub'
dc = DesiredCapabilities.HTMLUNIT
browser = webdriver.Remote(server, dc)
browser.get('http://localhost:8000')

Everything is ok after this. But when i'm trying to start Jenkins test:

from django.test import TestCase, LiveServerTestCase
from selenium.webdriver.common import proxy
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.remote.webdriver import WebDriver

class SeleniumTest(LiveServerTestCase):

    @classmethod
    def setUpClass(cls):
        p = proxy.Proxy({
        'proxyType': proxy.ProxyType().MANUAL,
        'httpProxy': '127.0.0.1:4444',
        })

        capabilities = DesiredCapabilities().HTMLUNIT
        cls.selenium = WebDriver(desired_capabilities=capabilities, proxy=p)
        super(SeleniumTest, cls).setUpClass()

    @classmethod
    def tearDownClass(cls):
        cls.selenium.quit()
        super(SeleniumTest, cls).tearDownClass()

    def test_javascript_basket(self):
        self.selenium.get('http://localhost:8000')

I'm getting following error, contained in traceback:

WebDriverException: Message: u'\n\n\nERROR: The requested URL could not be retrieved\n\n\n\n

What's going on? Why connect to Selenium server from Jenkins test isn't working?

python==2.7.3
Django==1.5
django-jenkins==0.14.0
selenium==2.33.0

UPDATE: If i'm using Firefox WebDriver instead of HTMLUNIT, Firefox opens after line 

cls.selenium = WebDriver(desired_capabilities=capabilities, proxy=p)

, but later raises above-described exception.

RESOLVED I simply add to setUpClass() method:

import os
. . .
    def setUpClass(cls):
        os.environ['NO_PROXY'] = '127.0.0.1'

I solved the problem this way (used a phantom-js instead of HTMLUNIT, because it's the only remaining stable version of code).

from django.test import LiveServerTestCase
from selenium import webdriver
from os import environ


class SeleniumTestCase(LiveServerTestCase):
    __test__ = False    

    @classmethod
    def setUpClass(cls):
        environ['NO_PROXY'] = '127.0.0.1'  # The key point

        cls.selenium = webdriver.PhantomJS(service_args=['--proxy-type=none'])    
        super(SeleniumTestCase, cls).setUpClass()

    @classmethod
    def tearDownClass(cls):
        cls.selenium.close()
        cls.selenium.quit()
        super(SeleniumTestCase, cls).tearDownClass()


class TestFoo(SeleniumTestCase):    
    def setUp(self):
        # do something before every test method runs
        pass
    def test_foo(self):
        # test
        pass
