Hi All, I have a client who is using DSWS for the first time. He has the correct prutil on his ID. When attempting to connect (after entering his username and password) he gets an error message, any ideas?

_get_token : Exception Occured

(<class 'requests.exceptions.ConnectionError'>, ConnectionError(MaxRetryError("HTTPSConnectionPool(host='product.datastream.com', port=443): Max retries exceeded with url: /DSWSClient/V1/DSService.svc/rest/GetToken (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x000001BF80939A20>: Failed to establish a new connection: [Errno 11001] getaddrinfo failed'))")), <traceback object at 0x000001BF8092B3C8>)

Hi @Alison.Quick, It looks like the application is not able to resolve the hostname because it is behind a proxy server.

Please ask the user to input the correct proxy information in the user configuration file:

[proxy_details]
server=***
username=***
password=***
port=***
ssl_verify]
certificate=

See the Readme file along with python samples here. User can get the correct proxy/firewall details from their network team.
