fixel app CORS error and 503 – Cross Origin

  • Hi,

    I’m receiving the following error in my Brave/Chrome browser inspector when I turn on GTM4WP. When I deactivate the error goes.

    Does GTM4WP use the API below? Or is it being called by something else in Google when the plugin is enabled?

    Is this something I need todo on my end to fix? Have I set something up wrong?

    Access to XMLHttpRequest at 'https://api.fixelapp.com/api/v2/grade/FXL-XXXX-XXXX' from origin 'https://example.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

    Fixel.min.js:1
    POST https://api.fixelapp.com/api/v2/grade/FXL-XXXX-XXXX net::ERR_FAILED 503

    And the following in FireFox
    Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://googleads.g.doubleclick.net/pagead/id. (Reason: CORS request did not succeed). Status code: (null).

    Thank you
