Hello
We have a doc with white ip list for this tool
https://support.magento.com/hc/en-us/articles/360029224131-The-Security-Scan-Tool-report-is-blank
But adding this ips also does not allow to scan the site:
52.72.230.169, 52.87.98.44, 52.86.204.1, at ports 80 and 443.
Does exists updated (extended ip list)
