I created a whitelist for content-src CSP like this:

   <policy id="connect-src">
            <value id="cloudflare" type="host">*.cloudflare.com</value>
            <value id="freshrelevance" type="host">*.freshrelevance.com</value>
            <value id="ga" type="host">*.google-analytics.com</value>

but the console log always shows this error:

[Report Only] Refused to connect to 'wss://am.freshrelevance.com/' because it violates the following Content Security Policy directive: "connect-src geostag.cardinalcommerce.com geo.cardinalcommerce.com 1eafstag.cardinalcommerce.com 1eaf.cardinalcommerce.com centinelapistag.cardinalcommerce.com centinelapi.cardinalcommerce.com *.amazon.com *.amazon.co.uk *.amazon.co.jp *.amazon.jp *.amazon.it *.amazon.fr *.amazon.es *.amazonpay.com *.amazonpay.co.uk *.amazonpay.co.jp *.amazonpay.jp *.amazonpay.it *.amazonpay.fr *.amazonpay.es mws.amazonservices.com mws.amazonservices.co.uk mws.amazonservices.co.jp mws.amazonservices.jp mws.amazonservices.it mws.amazonservices.fr mws.amazonservices.es *.trackedlink.net *.trackedweb.net *.dotdigital-pages.com api.comapi.com webchat.dotdigital.com *.cloudflare.com *.freshrelevance.com *.google-analytics.com 'self' 'unsafe-inline'".

the others whitelisted just fine

  • what is the full link you are trying to access from connect-src="full-link" but are not allowed?

Test to use the full link in your csp_whitelist.xml

<?xml version="1.0" encoding="UTF-8"?>
<csp_whitelist xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        <policy id="connect-src">
                <value id="freshrelevance" type="host">wss://am.freshrelevance.com/</value>

It works fins in my case when I try:

    var ws = new WebSocket("wss://am.freshrelevance.com/");
