Orders are being rejected because your whitelisted address no longer matches. How to confirm that is the cause, fix it correctly, and avoid the mistake that turns it into a longer problem.

A VPN looks like a cheap way to get a fixed address for broker whitelisting and usually is not. What shared exit nodes do, when a dedicated-IP VPN works, and the latency cost.

IP validation places a small real order and reverses it, proving your key, address, token and order routing all work. What the test does, what it costs, how to read a failure, and when to re-run it.
