So here is the setup for truecharts with traefik and the things needed for proper truecharts setup: https://truecharts.org/manual/SCALE/guides/getting-started

Do you also use cloudflare tunnel?

So I use traefik on my truenas server from the truecharts catalogue. If you need help there I can send you the corresponding links from the website later, I am not at the computer right now.

The problem is with nextcloud on my end. Some files just can’t get synced and bigger files won’t even go through. Perhaps something is misconfigured, but I think I red something, that cloudflare tunnels only support x gb of traffic at once.

That’s a good point. But that’s also the point where my tinkering won’t help me… Do you have a writeup or a yt video where nginx points to the wireguard VPN? Another question. If I set up the wireguard tunnel, how can I just route the traffic from traefik?
