My domain androz2091.fr is pointing to a single-node kubernetes cluster. Caddy is installed on the node (on the host, not inside k8s), and uses the cluster DNS to redirect to the right service.
Here is my Caddyfile. Here is my cluster documentation.
Unfortunately, every 30 to 50 requests when accessing my domain, I get this error:
poca@localhost:~ $ wget androz2091.fr

Where do I start looking for the problem?
I have no idea how to debug it (it's not even showing up at each request), and what piece of my cluster could be faulty. I can provide more information if needed.
