AWS Cloufront CDN Test

Hi guys,

i made a performance test yesterday after implementing a CDN (AWS CloudFront) into my website.
Even though the website seems to work fine (Images are being served through CDN) the test keep saying that CDN is not used effectivly.

AWS CloudFront CDN doesnt even show up in the used CDNs:

CDN’s Used:
www.googletagmanager.com : Google
analytics-udg.netdna-ssl.com : NetDNA
www.google-analytics.com : Google
js-agent.newrelic.com : Fastly
bam.nr-data.net :

I’ve read multiple older threads where CloudFront had some issues … is this still a thing?

Thanks in advance.
