I have a working (gunicorn, uvicorn, fastapi) setup with TLS provided by Let's Encrypt. I now want to add nginx or caddy to be a file server. It should listen on a couple of paths /static /videos and serve files requested on those paths.

So let's say the domain is [service.example.com](http://service.example.com). app-http is redirecting to app-https and listening for all paths on that domain

I've added an nginx container listening on the same domain with label

```auto

- "traefik.frontend.rule=Host(`japanese-joinery.ultrabob.com`) && PathPrefix(`/static/`, `/videos/`, `/screencaps/`)"

```

Nothing seems to get routed to the new container. I tried adding an inverted PathPrefix rule to the app-https service

```auto

- "traefik.frontend.rule=Host(`japanese-joinery.ultrabob.com`) && !PathPrefix(`/static/`, `/videos/`, `/screencaps/`)"

```

but I see a message in the logs

> level=error msg="error while parsing rule !PathPrefix(`/static/`, `/videos/`, `/screencaps/`): ! is not supported" entryPointName=http routerName=app-http@docker

I also wonder if this new service will be able to seamlessly use the certificate that is being procured for app-https or if I will need some config to make that happen.

I'm sorry for a bit of a broad question, I'm not sure how to simplify my setup to get to the core of things without either removing the TLS part altogether or do a new dns setup so I can test locally.

Looks fine.

If it is the same as your existing working domain it will be matched in the certificate store and used.

I run without a certificates resolver, ignore certificate errors and use curl's `--resolve` flag:

Thank you, that curl tip is really helpful. I think my problem must not have been with the rule but something else in the configuration. I did finally get it working.
