How do I change the proxy config

[Nubebuster]

I am running a docker registry and some layers are too big for the proxy. I need to change the max allowed size property of the proxy config. Where do I do that?

It needs to be something like
traefik.http.middlewares.my-requests.maxRequestBodyBytes=800000000

If I'm not mistaken, you should be able to achieve this by navigating to:
Servers > localhost > Proxy > Configuration.

Then, add Your line to the configuration file and save.

I added

  - traefik.http.middlewares.my-requests.maxRequestBodyBytes=800000000
  
  To the labels section and restarted everything. I still get a 413 http response

I found the issue. It was cloudflare dns proxy which has a file limit of 100MB.
