Portfolio Stream WebSocket Host Not Resolving (NXDOMAIN)

Developer API
1

I’m unable to connect with Portfolio Websocket Today
My portfolio-stream WebSocket connection suddenly stopped working on 23rd Feb 2026. It was working correctly till 19th Feb 2026 when I used it last time.

socket.gaierror: [Errno 11001] getaddrinfo failed

The authorize API is returning the following WebSocket host:
wsportfolioupdate-api.upstox.com
However, this hostname does not resolve in public DNS

I have also tried other things to debug on cmd with the help of ai below:
nslookup wsportfolioupdate-api[dot]upstox[dot]com 8.8.8.8

Server:  dns.google
Address:  8.8.8.8

*** dns.google can't find wsportfolioupdate-api.upstox.com: Non-existent domain

nslookup wsportfolioupdate-api[dot]upstox[dot]com 1.1.1.1

Server:  one.one.one.one
Address:  1.1.1.1

*** one.one.one.one can't find wsportfolioupdate-api.upstox.com: Non-existent domain

import socket
socket.gethostbyname(“wsportfolioupdate-api.upstox.com”)
socket.gaierror: [Errno 11001] getaddrinfo failed

I tried this approch too: Streamer Functions | Upstox Developer API
didn’t work..

Thank you.
