Getting 'ConnectionResetError' for URL 'https://api.india.delta.exchange', but works well for 'https://cdn-ind.testnet.deltaex.org'

Hi Everyone,
I had created the API credentials in the real account of delta exchange (https://www.delta.exchange/app/account/manageapikeys), but it is working only for the URL 'https://cdn-ind.testnet.deltaex.org' which I see is a demo endpoint.

How do I make it work on the real one 'https://api.india.delta.exchange' ?

Thanks a lot for anyone who helps,
