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

    raise ConnectionError(e, request=request)

Up to 2 attachments (including images) can be used with a maximum of 512.0 KiB each and 1.0 MiB total.

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, i come from china. China need use the ip address, not the hostname to access it.

@lei.cheng, oh, ok. If you type the following URL in a browser, can you see a page ?

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.
