You can use the requests Python library to check network settings. Please try the following code in the same environment.

import requests

url = 'https://product.datastream.com/DSWSClient/V1/DSService.svc/rest/GetToken'
myobj = {"Password": "<username>", 
         "Properties": [{"Key": "__AppId", "Value": "PythonLib-1.1.0"}], 
         "UserName": "<password>"}

x = requests.post(url, json = myobj)
print(x.status_code)
print(x.text)

You may need to enable HTTP logging in Python.

import logging
import http.client
 
http.client.HTTPConnection.debuglevel = 1
 
logging.basicConfig()
logging.getLogger().setLevel(logging.DEBUG)
requests_log = logging.getLogger("requests.packages.urllib3")
requests_log.setLevel(logging.DEBUG)
requests_log.propagate = True

Hello @mathieu.duarte

What is the version of DatastreamDSWS in your environment?

You can check the version from the following command:

pip show DatastreamDSWS

The latest version of the API is version 1.0.10 (as of Apr 2022), if you are using a lower version, please try to update the library.

Hi @wasin.w ,

I'm already using 1.0.10 so I guess the problem does not come from this.

Hello @mathieu.duarte

Thank you for the information. I can connect to DSWS using DatastreamDSWS 1.0.10.

Are there any changes in your network?

Please test with the http://product.datastream.com/DswsClient/Docs/TestRestV1.aspx page.

First, use the Get Token method to get a token.

Then, use the token with the Data (HTTP GET) method to get the data. Next, check the response.

@wasin.w ,

I tested with your page and following the "Get Token" method I managed to obtain an example of result with both "Get Data" and the "Data (HTTP GET)"

Hi @Jirapongse ,

Following the command "x = requests.post(url,json=myobj)" the station remains frozen with just: "DEBUG:urllib3.connectionpool:Starting new HTTPS connection (1): product.datastream.com:443"

Nothing else happens.

Would you know what I should do next ?

Hello @mathieu.duarte

I have tested the steps suggested by @Jirapongse.The result is shown below.

According to your statement, it may be a network issue between your Python environment and Datastream. I highly recommend you contact your local IT support to verify the network setting in your environment.

Thanks for your answers. Following some interaction with my local IT support we've adjusted some proxy parameters and it solved this problem.
