Yes I use the CDN plugin because I use one of the AWS services S3. If I disable the plugin it will certainly interfere with my web performance. Is there no other way to fix it?
If you don’t want to disable it then you need to fix it because now it doesn’t work for some files on your website like the one for our header builder.
Try to contact this service support for help since we don’t have an instruction for this. We are using KeyCDN on our demo and it works fine with all the resources.
