N8n selfhosted docker behind traefik

[Juri]

I try to run n8n on a vps in a docker, behind traefik and cloud flare. the problem is, that the webhook links have the port number inside. test url I get to work, but production still have the port inside the link

if I try to set n8n_port to 443 I get bad gateway or 502 from cloud flare

services:
  n8n:
    image: n8nio/n8n:latest
    container_name: n8n
    restart: unless-stopped
    env_file:
      - .env
    environment:
      - N8N_BASIC_AUTH_ACTIVE=${N8N_BASIC_AUTH_ACTIVE}
      - N8N_BASIC_AUTH_USER=${N8N_BASIC_AUTH_USER}
      - N8N_BASIC_AUTH_PASSWORD=${N8N_BASIC_AUTH_PASSWORD}
      - N8N_PROTOCOL=https
      - N8N_HOST=n8n.wesa-dress.de
      - WEBHOOK_URL=https://n8n.wesa-dress.de
      - N8N_EDITOR_BASE_URL=https://n8n.wesa-dress.de
      # Du lässt N8N_PORT entweder weg oder setzt ihn auf den internen Wert (5678)
    volumes:
      - /home/ubuntu/docker/n8n/data:/home/node/.n8n
    networks:
      - proxy
    # Hinweis: Entferne hier jegliche "ports:"-Angabe, damit n8n nicht direkt vom Host erreichbar ist.

If you are running n8n behind Traefik, you wouldn’t configure n8n itself to use https. Seems like you have a mixture of conflicting stuff configured. It might help to review Self Hosting n8n with Docker and Traefik/LetsEncrypt (for https) or one of the other guides for setting up Traefik in front of something else.

The key thing you might be missing is that https (ssl) will be terminated/handled by either Traefik or n8n. Not both.
