Cors problem - need a hand

Hi guys I got problem with cors and cant figure it out:

Access to script at ‘’ from origin ‘’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

and I have trying for few hours but my API is not showing on my main domain just on netlify.

Can someone help newbie out

You might have resolved it as I’m not seeing that error on your website anymore.
