[Cedric]

Hello,
after multiple searches, I can’t find the solution.
I can no longer connect my nodes because of this new VPS server installation.The certificate is managed by traefik
I’ve tested several browsers, checked the validity of the certificate.

My docker-compose.yml

version: "3.7"

services:
  traefik:
    image: "traefik:v3.1"
    container_name: "traefik"
    command:
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entryPoints.web.address=:80"
      - "--entryPoints.websecure.address=:443"
      - "--certificatesresolvers.myresolver.acme.tlschallenge=true"
      - "--certificatesresolvers.myresolver.acme.email=votreemail"
      - "--certificatesresolvers.myresolver.acme.storage=/letsencrypt/acme.json"
      - "--log.level=DEBUG"
    ports:
      - "80:80"

    volumes:

It looks like your topic is missing some important information. Could you provide the following if applicable.

• n8n version:
• Database (default: SQLite):
• n8n EXECUTIONS_PROCESS setting (default: own, main):
• Running n8n via (Docker, npm, n8n cloud, desktop app):
• Operating system:

Hey @Cedric,

It looks like you have followed a very old set of instructions to get n8n up and running but looking at your images I can see what the issue is.

Your SSL Labs test is using n8n.automateddigital.fr but the application is configured to use n8n.automateddigital.fr:5678 so they tests are not checking the same thing but n8n is also not listening on 5678 for https connections and won’t have the Traefik cert on it.

In your n8n config remove the below as they are not needed…

N8N_BASIC_AUTH_ACTIVE
N8N_HOST
N8N_PORT
N8N_PROTOCOL
WEBHOOK_TUNNEL_URL

And add

WEBHOOK_URL=https://n8n.automateddigital.fr

Then stop and start n8n and you should be good to go.
