Hi Sandra,
This is possibly a security issue, you either need to bypass the .svg files so that those files are requested at your main domain or allow your CDN to serve those type (SVG) of files.
I can’t confirm if you have that options on your CDN settings though, as the credentials you provided above does not work.
In any case please contact your CDN support on how you can apply those settings effectively.
Also as this happen after you edit your child theme, please clear/purge all your caches just to make sure your site is serving the updated files.
Thanks,
