HTTP/1.1 413 Payload Too Large with Cloudflare Tunnel -> Ngnix -> Deconz

I’m trying to configure access to this container behind nginx, however I’m running into HTTP/1.1 413 Payload Too Large when trying to access the site. My current config is cloudflare tunnel → nginx → deconz, however if I remove cloudflare tunnel (by accessing from locally via nginx → deconz) it works correctly.

I’m not seeing this issue for any other of my sites behind the tunnel (home assistant for example), so I think the problem is with deconz however I’m not entirely sure as even with dbg-http I’m not seeing anything in the logs for a request.
Edit: I ran TCPDUMP in the container and I can see the requests hitting deconz, logs below.

Note: I was originally using deconz-docker, however the issue still occurs if I install deconz outside of a docker container)

Is there any suggestions how I can debug this further? (Included at are the sanitized nginx config and logs which may have something useful in there.
