Errors on boot up of HA

Hi all anyone know what the two errors are

File “/srv/homeassistant/homeassistant_venv/lib/python3.4/site-packages/requests/”, line 374, in prepare_url
scheme, auth, host, port, path, query, fragment = parse_url(url)
File “/srv/homeassistant/homeassistant_venv/lib/python3.4/site-packages/requests/packages/urllib3/util/”, line 195, in parse_url
raise LocationParseError(url)
requests.packages.urllib3.exceptions.LocationParseError: Failed to parse: None:None


My best guess would be there is something in your config that should be a URL but isn’t one.
