Hi,
I want to choose to serve analytics.js/gtag.js from Cloudflare by providing the base URL. This is a setting in CAOS plugin. I entered (Cloudflare.my domain) but GTMetrix waterfall chart showed that request failed. Any suggestion will be highly appreciated.
If you are talking about the Wordpress Plugin CAOS please search for support at their forum or directly from their devs since in this regard Cloudflare does not have anything to do with it.
