I also face that kind of issues with my website of https://xxxtentacionmerch.net/ and the icons upload but not show in the live session. Cross-domain origin means your website is running on “HTTP” protocol and its try to access data from the “https” protocol and due to this reason icons are not loading in your website.
I am finding a really big difficulty in finding the URL because it was change whenever I made it like I made a URL of the fishing license near me and then their inner link has been automatically changed.
