Thank you for your hard work.

I'm currently using the Python API for Datastream DSWS, and I'm experiencing a timeout error when calling the Datastream object. I'm posting this question to inquire about the possible causes.

    Thank you for reaching out to us.

    I got a different error.

    Please run the following code before calling the datastream library to enable the debug log in the urllib3 library.

    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
