Failed to fetch Error

We recently switched from Sucuri to Cloudflare.

After doing so, we had errors on our PDF Embedder module that says “Failed to fetch Error: URL to the PDF file must be on exactly the same domain as the current web page. Click here for more info”

I found a way to fix it by adding “www.” on each embedded PDF, however, we’ve got hundreds of PDFs embedded on our site, is there a way to be able to fix all by just changing some setting?

We have reached out to Cloudflare and they helped fix the URL redirect, but we’re still getting the error on our existing PDFs.

Thank you in advance?
