How can I confirm if my IP address is properly whitelisted?

To confirm whether the Stock Sync IP (52.20.189.51) is properly whitelisted by your supplier, you can perform a few quick checks.

Test the connection using your feed method (FTP, SFTP, HTTP, or API). If the feed loads normally after whitelisting, the IP is accepted.
If the connection still fails, ask your supplier to check their firewall logs for any blocked or denied requests coming from 52.20.189.51. This is the most reliable way to confirm whether the whitelist is working.
You may also test the connection manually using an external tool (e.g., FileZilla for FTP/SFTP). If the test times out or refuses connection, the IP likely isn’t fully whitelisted or the required port is still blocked.
Ask your supplier to verify that the whitelist applies to the exact endpoint and port being used, as some servers require per‑path or per‑service whitelisting.

Once the supplier confirms successful access in their logs and the connection test succeeds, the IP is correctly whitelisted.
