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
Yes, it is the same error.
I assume that the headers format is incorrect.
I will contact the product team to verify what the problem is.
I tested it again. I think the probelm has been resolved.
Could you please confirm if the problem has been resolved?

We are seeing the same issue. From what I can tell, the config of the webserver must have changed. It would be great to get this fixed as we rely on the datastream rest api!
