Bug: Broken Pipe in Kubernetes deployment

[IngwiePhoenix]

Hello there!

I just wanted to share a file with my friends from my Plik instance running inside a k3s environment.

The way that ingress is configured is actually:
plik deployment -> Traefik -> VPN <- Caddy <- World

Somewhere in that chain, and apparently quite early, I encounter this error:

[11/28/2024 20:04:14][WARNING ][[10.42.0.195][dnXYxqnjpSIXfjpN]] error while copying file to response : write tcp 10.42.0.17:8080->10.42.0.1:39416: write: broken pipe

What reasons could there be for this situation? Here is my config:
