when I try to connect to https://smartapi.upstox.com from my AWS EC2 instance (IP: 34.232.103.54), I’m receiving the following error:

curl: (28) Failed to connect to smartapi.upstox.com port 443: Connection timed out

This confirms it’s a network-level access issue (port 443 blocked), and I kindly request you to ensure port 443 is open/accessible from my instance.
