[xml2rfc] Problems running xml2rfc on Fedora 30

[Robert Moskowitz <[e-mail]>]

This is the first time running xml2rfc on my new, Fedora 30 build.

I had done the 'pip install xml2rfc' when I built this system a couple 
months ago.  Today I went to run it and got errors.  SO I grabbed the 
xml from a draft I worked with back on Fedora 28 and got the following 
for my efforts:

$ xml2rfc draft-moskowitz-hierarchical-hip-06.xml
Parsing file draft-moskowitz-hierarchical-hip-06.xml
Traceback (most recent call last):
   File "/usr/bin/xml2rfc", line 11, in <module>

     xmlrfc = parser.parse(remove_pis=options.remove_pis, normalize=True)

     include=True, line_no=getattr(element, 'sourceline', 0))

     result = self.cache(url)
   File "/usr/lib/python2.7/site-packages/xml2rfc/parser.py", line 368, 
in cache
     r = session.get(url)
   File "/usr/lib/python2.7/site-packages/requests/sessions.py", line 
546, in get
     return self.request('GET', url, **kwargs)
   File "/usr/lib/python2.7/site-packages/requests/sessions.py", line 
533, in request
     resp = self.send(prep, **send_kwargs)
   File "/usr/lib/python2.7/site-packages/requests/sessions.py", line 
646, in send
     r = adapter.send(request, **kwargs)
   File "/usr/lib/python2.7/site-packages/requests/adapters.py", line 
498, in send
     raise ConnectionError(err, request=request)
requests.exceptions.ConnectionError: ('Connection aborted.', 
BadStatusLine('No status line received - the server has closed the 
connection',))


Please advise me on how to fix this.  I can provide the xml if needed.
