Behind Traefik : Too many redirect

Hello,
I'm trying to do my best but it doesn't work : **Too many redirect**
I'm behind traefik and that is the docker-compose template generated :
Do you see something wrong?

```

```

I have a wildcard on jpj.ovh
And I want to test Wordpress as subdomain like lf.jpj.ovh
I don't know If I have to use the same networks.
Any idea ?
