Microsoft Office 365 connector & proxy

Hi, my ucs is behind the corporate proxy, trying the microsoft 365 connector fails to talk to azure reports the problem below:

Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.7/univention/office365/", line 539, in _get_azure_certs
    fed = requests.get(federation_metadata_url.format(adconnection_id=adconnection_id), proxies=cls.proxies)

    return request('get', url, params=params, **kwargs)

    r = adapter.send(request, **kwargs)
  File "/usr/lib/python2.7/dist-packages/requests/", line 487, in send
    raise ConnectionError(e, request=request)
ConnectionError: HTTPSConnectionPool(host='', port=443): Max retries exceeded with url: /841e1a0d-1019-1302-9a99-4e60b32b46d3/federationmetadata/2007-06/federationmetadata.xml (Caused by NewConnectionError('<requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7f96902016d0>: Failed to establish a new connection: [Errno 110] Connection timed out',))

does this mean that the connector is not compatible with the proxy?

thank you.

Hi, removing the proxy makes the connector work correctly.
