Alright I've solved the issue by myself. The problem was that my agent used internal k8s domain names. I've changed them (in agent's helm values) to real ones, added certificates, set REQUESTS_CA_BUNDLE env var to point to my custom ca cert bundle and voila - debug samples are shown

Here's what I see. And the url of the image is k8s internal url
like None

If I substitute the internal address part ( None with actual address I can see the image ( None )

Here's my values.yaml cleaned from keys.

Also worth to mention that I'm using helm chart 7.11.4

Hi @<1585078752969232384:profile|FantasticDuck7> , can you add some information? Are the debug samples being logged and just not showing in the webUI or they are not available at all? Are debug samples logged to the files server or some other storage?
