Hi @grabnerandi ,

Installation is being executed on EC2 machine from AWS. I have followed the steps in the .readme file precisely under release-0.8.0. Tried many times on many different virtual machines, but I am still getting same error after starting the installation with this command:

./install-keptn-on-k3s.sh --controlplane --provider aws --with-dynatrace --with-demo dynatrace --letsencrypt --with-gitea

Its going fine through many steps (Please see attached file log below), but when reaching keptn installation step it fails here:

Seems like https://keptn.34.238.152.105.nip.io is just responding with 404 on all requests. It used to work for me on earlier releases with xip.io, any new issue now with nip.io?

I am attaching a full log output of my terminal session.
