I got this error message in the epub file:

Failed feed: Politics
<urlopen error [Errno -2] Name or service not known>

When I run urllib2.urlopen directly in Python, I got this error:

>>> import urllib2
>>> a=urllib2.urlopen('http://www.matichon.co.th/rss/news_article.xml')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/urllib2.py", line 126, in urlopen
    return _opener.open(url, data, timeout)
  File "/usr/lib/python2.6/urllib2.py", line 391, in open
    response = self._open(req, data)
  File "/usr/lib/python2.6/urllib2.py", line 409, in _open
    '_open', req)

    raise URLError(err)
urllib2.URLError: <urlopen error [Errno -2] Name or service not known>

What is the problem? Please suggest me.
