Upstox Webhook Not Hitting My Server

I’m facing an issue where the Upstox token webhook (/api/upstox/notifier) works fine when tested via Postman — logs appear and DB is updated. But when Upstox triggers it after login, nothing shows in Flask or NGINX logs.

@samseer_mannissery Could you please share the Notifier URL? I will coordinate with the security team to get it whitelisted.

Thanks.
The Notifier URL is: https://traddapp.com/api/upstox/notifier
