why to say "Max retries exceeded with url: /RestApi/v1/Authentication/RequestToken"

follow the 20419 question, i used the 

https://192.165.219.152/RestApi/v1/Authentication/RequestToken in the python demo (TRTH_OnDemand_IntradayBars),but still Traceback (most recent call last):
  File "TRTH_OnDemand_IntradayBars.py", line 52, in <module>
    r1 = requests.post(requestUrl, json=requestBody,headers=requestHeaders)
  File "/usr/lib/python2.7/site-packages/requests-2.18.4-py2.7.egg/requests/api.py", line 112, in post
    return request('post', url, data=data, json=json, **kwargs)
  File "/usr/lib/python2.7/site-packages/requests-2.18.4-py2.7.egg/requests/api.py", line 58, in request
    return session.request(method=method, url=url, **kwargs)
  File "/usr/lib/python2.7/site-packages/requests-2.18.4-py2.7.egg/requests/sessions.py", line 508, in request
    resp = self.send(prep, **send_kwargs)
  File "/usr/lib/python2.7/site-packages/requests-2.18.4-py2.7.egg/requests/sessions.py", line 618, in send
    r = adapter.send(request, **kwargs)
  File "/usr/lib/python2.7/site-packages/requests-2.18.4-py2.7.egg/requests/adapters.py", line 508, in send
    raise ConnectionError(e, request=request)
requests.exceptions.ConnectionError: HTTPSConnectionPool(host='hosted.datascopeapi.reuters.com', port=443): Max retries exceeded with url: /RestApi/v1/Authentication/RequestToken (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x1dda390>: Failed to establish a new connection: [Errno 110] Connection timed out',))

correct it:

requests.exceptions.SSLError: HTTPSConnectionPool(host='192.165.219.152', port=443): Max retries exceeded with url: /RestApi/v1/Authentication/RequestToken (Caused by SSLError(CertificateError("hostname '192.165.219.152' doesn't match 'hosted.datascopeapi.reuters.com'",),))

@lei.cheng, can you try the following code which disables SSL verification?

r1 = requests.post(requestUrl, json=requestBody,headers=requestHeaders,verify=False)

@lei.cheng,

Can you try with the hostname instead of the IP address in the data request ?

This for two reasons:

  1. The IP address mapping can change in the future
  2. The SSL certificate is bound to the hostname. Using an IP address with a TLS secured channel will raise a Security Exception in your browser or API libraries, and stop you from connecting to the service.

Hi, Christiaan

Please see below ticket another client raised before, china clients can't access DSS using Hostname, so use the IP address will be a workaround. thanks.
