CORS help, and that’s not a beer issue

I’m using a plugin **Bulk Product Sync with Google Sheets PRO** and getting this error in my console Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at [https://] (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 500.

I only have access to the CDN, so I tried a plugin **HTTP Headers** for HTTP headers management including security, access control,, (CORS), caching, compression, and authentication. I also tried **Enable CORS**

Would anyone be able to help or give me a direction? I’ve talked to the hosting with no help yet.
