| I am an Upstox Plus user and am unable to establish a Market Data Feed V3 WebSocket connection. REST API authentication and other REST market-data APIs are working correctly. I tested the WebSocket independently of my application using the official Upstox Python SDK: upstox-python-sdk: 2.30.0 MarketDataStreamerV3 Only one instrument: NSE_INDEX |
Nifty 50 Mode: full Only one WebSocket connection The connection fails during the WebSocket handshake: Handshake status 403 Forbidden I also tested the V3 market-data authorization endpoint separately. |
