Hello @trisha.gehlot,

The error indicates that your Python app is unable to reach the DSS servers. If you are in a corporate network, behind a proxy/firewall, you should enable the proxy parameters for the Python requests module or use a different network with direct route to internet for requesting data.

You can try to use this environment variable:

set https_proxy=http://YOUR_PROXY_HOSTNAME:YOUR_PROXY_PORT

Hello @Gurpreet, Thank you for your response!!

But extraction happens for most of the data -

INFO Extraction verification successful for 20-08-2024

INFO Processing Chunk No.1155 with len:500 Instrument Range VOD070P28.L<-->NWG22000A27.L

INFO Response code when attempting to retrieve token from DataScope: 200

It is strange that the connection fails only some of the time. The INFO messages are being generated by your application and not DSS. Can you check in the application code and maybe enable network traces to see what is happening. Are there multiple proxy servers in your network. It might help to get your network administrators involved as well.
