no logs shipped

I'm trying to collect my Docker Container logs to logDNA, but I'm struggling. My docker-compose.yml:

version: "3"

services:
  logdna:
    image: logdna/logspout
    container_name: logdna
    restart: unless-stopped
    # ports:
      # - "127.0.0.1:5000:80"
    environment:
      - "LOGDNA_KEY=a692fc7xxxxx"
      - "FILTER_NAME=portainer_portainer_1"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"

docker-compose logs prints:

logdna    | # logspout v3.2.6-custom by gliderlabs
logdna    | # adapters: raw syslog tcp udp logdna
logdna    | # options : persist:/mnt/routes
logdna    | # jobs    : http[logs,routes]:80 pump routes
logdna    | # routes  :
logdna    | #   ADAPTER ADDRESS CONTAINERS              SOURCES OPTIONS
logdna    | #   logdna          portainer_portainer_1           map[]

running docker exec -it logdna logspout prints:

[...]
2019/08/22 09:39:13 http[logs,routes]:80 ended: listen tcp 0.0.0.0:80: bind: address already in use

In my Onboarding Backend on https://app.logdna.com it's waiting for logs. I've tried setting a fixed localhost port in my docker-compose.yml but nothing changed. The portainer/portainer container is running on localhost only as well. I use a traefik:v2.0 container as a nginx proxy which is using port 80 and 443. Can somebody help me?

OK, nevermind. logdna seems a little bit slow on the initial process
