Magento 2.4.7 checkout not working

In your custom module, create a config.xml file under etc folder, paste the provided code into that file, and then run the following command:

php bin/magento cache:flush

<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../Store/etc/config.xsd"> <default> <csp> <mode> <storefront_checkout_index_index> <report_only>1</report_only> </storefront_checkout_index_index> </mode> </csp> </default> </config> 

Currently it seems like the Content Security Policy mode in your store is set to block the urls violating content security policy. There isn't as such any setting in admin which you can use to set it back to "report only", but you can do so using database.

Run following query on your database.

update core_config_data set value = 1 where path = 'csp/mode/storefront/report_only'; 

Also, going forward if you want to keep a CSP whitelist, you can follow corresponding guide on devdocs here

You just have to create csp_whitelist.xml mentioning the domains you want to allow and which policies you want to allow for that specific domain. The list of policies is already mentioned on the document.
