Background: I have Cloudflare setup with my website, and read/write permissions allowed, Printful was syncing previously a few months ago but is no longer syncing, in this time I have not added any new plugins and I have reached out to Printful but they have been unable to help directly, I have also tested by removing all of my plugins and theme but this did not resolve the issue.

Please help me identify the issue and resolve.

Thanks in advance.
