Hello dear Traefik community,
I have a question about my Traefik setup. We are using Traefik as a proxy to reach our services in Hashicorp Nomad. The services register in Consul, which allows Traefik to get the Nomad services and other information like destination IP and port via the Consul Catalog.
We need to make sure that even if an application has a "Dead" status in Nomad, and thus is not registered in Consul, Traefik will respond with a 503 code and not 404.
For this I made exactly the changes described in the Traefik FAQ:
> **[Traefik Getting Started FAQ - Traefik](https://doc.traefik.io/traefik/getting-started/faq/#404-not-found)**
>
> Check out our FAQ page for answers to commonly asked questions on getting started with Traefik Proxy. Read the technical documentation.
Unfortunately Traefik still refuses to send the requested code and stays with the 404.
Does anyone here maybe have an idea what I have overlooked?
Or is there a better solution than implementing a CatchAll rule in the meantime?
Traefik Configuration:
- traefik.toml
```auto
[respondingTimeouts]
writeTimeout = "300s"
[entryPoints]
[entryPoints.http]
address=":80"
[entryPoints.http8080]
address=":8080"
[entryPoints.http.forwardedHeaders]
insecure = true
[entryPoints.http8080.forwardedHeaders]
insecure = true
[entryPoints.traefik]
address=":8081"
[api]
dashboard=true
insecure=true
[providers.consulCatalog]
refreshInterval="1s"
prefix="traefik"
exposedByDefault=false
[providers.consulCatalog.endpoint]
address="127.0.0.1:8500"
scheme="http"
[log]
level="ERROR"
[accessLog]
[accessLog.fields.headers]
defaultMode = "keep"
[providers.file]
filename="dynamic.yaml"
```
- dynamic.yaml
```auto
http:
routers:
catchall:
# attached only to web entryPoint
entryPoints:
- "http"
- "http8080"
# catchall rule
rule: "PathPrefix(`/`)"
service: unavailable
# lowest possible priority
# evaluated when no other router is matched
priority: 1
services:
# Service that will always answer a 503 Service Unavailable response
unavailable:
loadBalancer:
servers: {}
```

Do you have a `providers.file` to read the dynamic config file?

Did you check the log, is it read? I trust more in absolute file names with full path.
