Cloudflare Tunnel on Kubernetes

Hey there people!

I trust some of you have faced similar issues. I’ve set-up a Tunnel as a sidecar container in our Kubernetes Cluster. Everything works like a charm, except one thing. No matter what I do, I get a Bad Gateway 502 as soon as I add my desired service. (To mention that the tunnel is set-up via the Zero Trust Dashboard) Although I’ve tried it both ways, also locally.

What I also need to mention is that there is an Ingress (GKE) and we’re already proxying a lot of our services to Cloudflare (A records) with some CF firewall rules. Naturally, If I add an already existing A record to the tunnel I get an Error 1000.

What could I be missing? Thank you all in advance!
