Messenger bot的ConnectionError

Question

我正在將Messenger機器人與pymessenger一起使用（在此處鏈接https://github.com/davidchua/pymessenger ）。 有時，當我嘗試使用bot.send_text_message（）或其他函數之一向用戶發送消息時，發送python軟件包的消息時，出現以下錯誤：

  File "C:\Python27\lib\site-packages\pymessenger\bot.py", line 29, in send_text_message
    return self._send_payload(payload)
  File "C:\Python27\lib\site-packages\pymessenger\bot.py", line 76, in _send_payload
    result = requests.post(self.base_url, json=payload).json()
  File "C:\Python27\lib\site-packages\requests\api.py", line 111, in post
    return request('post', url, data=data, json=json, **kwargs)
  File "C:\Python27\lib\site-packages\requests\api.py", line 57, in request
    return session.request(method=method, url=url, **kwargs)
  File "C:\Python27\lib\site-packages\requests\sessions.py", line 475, in request
    resp = self.send(prep, **send_kwargs)
  File "C:\Python27\lib\site-packages\requests\sessions.py", line 585, in send
    r = adapter.send(request, **kwargs)
  File "C:\Python27\lib\site-packages\requests\adapters.py", line 467, in send
    raise ConnectionError(e, request=request)
ConnectionError: HTTPSConnectionPool(host='graph.facebook.com', port=443): Max retries exceeded with url: /v2.6/me/messages?access_token=<my_token> (Caused by NewConnectionError('<requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x00000000422A40B8>: Failed to establish a new connection: [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond',))

我以為也許我對Facebook進行了太多請求，但是使用我的機器人只是我，而我正在執行的請求數量是正常聊天的次數，所以我想應該是其他事情，但是我沒有得到什么。 我正在使用ngrok進行回調。

嘗試捕獲HTTPSConnectionPool異常並查看其args以查看詳細信息，例如：

except HTTPSConnectionPool as e:
    e.args
