I just wanted to post this in case someone else runs into this issue. If you are utilizing the custom Publit.io's CNAME feature with Cloudflare and run into an issue such as "Error 1101 Doesn't allow Hotlinking" it is because you are proxing the CNAME record. To resolve this issue turn the proxy status to "DNS Only" (AKA orange cloud off, turn it to a gray cloud).
