Datastream DSWS Time out Error

sjh0724

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

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!

Thank you Jirapongse. I'm sharing the results of running the script as you guided.

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?
