SSL Certificate Error when using the Datastream Web Service - hostnames don't match

We are using the datastream web api in a production GKE environment. We are getting intermittent SSL Errors.

/dswsclient/V1/DSService.svc/rest/GetDataBundle (Caused by SSLError(CertificateError("hostname 'product.datastream.com' doesn't match 'datastreamwide.refinitiv.com'")))


This seems like a refinitiv networking/infrastructure issue. Is there anything we can do to fix this? It's causing problems for our production models.

@walter01

Thanks for reaching out to us.

I checked against the DatastreamPy 1.0.12 library and it works fine with the product.datastream.com web service. This product.datastream.com URL is the default URL for the DatastreamPy 1.0.12 library.

You may need to verify the name and version of the application's Datastream library.

I also checked those URLs (datastreamwide.refinitiv.com and product.datastream.com) against the SSL Checker. The SSL Checker returns the correct name.

Yes, you are correct. It should be the problem on the server side so you can contact the Refinitiv Datastream Web Service support team directly via MyRefinitiv.

I hope that this information is of help.
