Is there a reason I would be getting the 400 bad request after setting up the CDN? The test image doesn’t exist but the plugin is activated and linked to my account.
I did a “check” and then things seemed to start working.
Sorry for the delay in my response.
After adding your site to the CDN, it can take a few minutes for it to populate throughout our network. That may have accounted for the initial error and subsequent resolution.
