Can I whitelist an AWS Elastic IP instead?

Until you rebuild the instance. A proxy in front of a dedicated Algo-IP address survives VM replacements.

Upstox API IP Not Whitelisted — Stop SDK Direct Connections

Upstox origin / IP error even after whitelist? The SDK often opens a direct socket. Force HTTP proxy 443 at process level for REST and market data.

Whitelist path

Upstox developer console → app → allowed IPs. Paste the dedicated Algo-IP IPv4. Confirm IPv6 support in the form; do not guess.

Why the SDK bypasses your proxy

Many official SDKs create their own HTTP adapter. Setting proxies on one requests.Session is not enough if market-data code uses urllib or a WebSocket library with no proxy argument. Export HTTP_PROXY / HTTPS_PROXY for the process, then restart the bot.

Verify before live orders

Call api.ipify.org with the same client the SDK uses. If you see the home WAN, Upstox will too. Setup: /brokers/upstox.
