504 Gateway Timeout

M4gie · October 26, 2019, 8:47am

Hi, I migrate my Traefik v1 to v2. I have two react apps and one node API. My react apps are working but when I try to call my API I got a 504 Gateway Timeout.

This is my docker-file configuration:

services:
  traefik:
    image: traefik:v2.0
    container_name: traefik
    ports:
      - "80:80"
      - "443:443"
    command:
      - "--log.level=DEBUG"
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--certificatesresolvers.m4gie.acme.httpchallenge=true"

      - "--certificatesResolvers.serv-hytale.acme.tlsChallenge=true"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
      - "./letsencrypt:/letsencrypt"

Hello,

could you can try something like that:

I'm still having the same error, that's my traefik logs but I didn't found anything interesting.

My new Docker compose configuration:

services:
  traefik:
    image: traefik:v2.0
    container_name: traefik
    ports:
      - "80:80"

      - "--providers.docker=true"

I change my configuration to use networks and now I have a 502 Bad Gateway

My new configuration:

Solved

My 504 error was fixed, it was because my networks were not setup. To fix my 502 error, I changed my API host HOST: "127.0.0.7" to HOST: "0.0.0.0"
