I managed to solve this finally. At the end of the report, it says: `was delivered in report-only mode, but does not specify a 'report-uri'; the policy will have no effect. Please either add a 'report-uri' directive, or deliver the policy via the 'Content-Security-Policy' header.` This is not saying that the the domain values for each of the listed policies are not whitelisted, they are by default (this error made believe they weren't until I really looked at it closer). It's saying that there is no `report-uri` directive. From the [devdocs][1], it says: `Regardless of restrict or report-only mode, CSP violations may be reported to an endpoint for collection. The URL to use for reporting by browsers can be configured in your custom module’s config.xml file:` <?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Store:etc/config.xsd"> <default> <csp> <mode> <storefront> <report_uri>http://csp-reporting-service.com/my-project/endpoint</report_uri> </storefront> <admin> <report_uri>http://csp-reporting-service.com/my-project/endpoint</report_uri> </admin> </mode> </csp> </default> </config> **By default, CSP sends errors to the browser console, but can be configured to collect error logs by HTTP request. In addition, there are a number of third-party services that you can use to monitor, collect, and report CSP violations. So, either configure it to be reported to the error logs by https request, or create a custom module and configure the report_uri directive with your the CSP reporting service of your liking.** [https://devdocs.magento.com/security/content-security-policy-overview.html][2] [1]: https://devdocs.magento.com/guides/v2.3/extension-dev-guide/security/content-security-policies.html#report-uri-configuration [2]: https://devdocs.magento.com/security/content-security-policy-overview.html
