Nikola connection refused

Hi there,
getting some emails since several days, about firewall “down”.
Nikola manual complains about connection error.

~# /usr/share/nikola/bin/
Traceback (most recent call last):
  File "/usr/bin/nikola", line 134, in <module>
    logger = get_logger(options.debug)
  File "/usr/lib/python2.7/site-packages/nikola/", line 32, in get_logger
    sys_handler = logging.handlers.SysLogHandler(address="/dev/log")
  File "/usr/lib/python2.7/logging/", line 761, in __init__
  File "/usr/lib/python2.7/logging/", line 789, in _connect_unixsocket
  File "/usr/lib/python2.7/", line 228, in meth
    return getattr(self._sock,name)(*args)
socket.error: [Errno 111] Connection refused

Any ideas aynone how to debug and fix?
