There are many many reasons why this would happen. Are you able to provide the test URL that the plugin provides in the main settings page?
Two of the most common reasons why this would happen :
- The settings for the site url doesnt match your url. Note that “site.com/” and “site.com” are treated differently by the system. Make sure the url defined in the CDN dashboard settings matches exactly what your site url is.
- Your web hosting provider is blocking our CDN endpoints mistakenly thinking it is automated bot traffic
We can try to rule out the issue. Step 1 would be to provide the test URL so I can see what is happening.
Thank you
