Hi,

my target is a server with, for example, nextcloud, mail and some other things.

At the moment, traefik runs with dashboard. Nextcloud rans with https and letsencrypt.

In the settings of nextcloud are some warnings:

```auto
* The reverse proxy header configuration is incorrect, or you are accessing Nextcloud from a trusted proxy
* The "Strict-Transport-Security" HTTP header is not set to at least "15552000" seconds
* Your web server is not properly set up to resolve "/.well-known/caldav"
* Your web server is not properly set up to resolve "/.well-known/carddav"

```

My docker-compose.yaml

```auto
version: "3.3"

Thanks for your help
