Gateway timeout after some reverted changes

jaytonic · July 3, 2023, 7:49pm

Hi,

I was testing to add a new container, and since I was not having the time to finish, I temporarly reverted by my config to the last working version, but now when I try to access my previously working services, it just says "Gateway Timeout".

If I try to access them directly(without going through Traefik), it seems to work.

version: "3.9"

services:
  traefik:

What did I manage to mess up? Since I was trying to setup wireguard, I did tried some network stuff, but I'm totally sure that the docker-compose file I reverted back too is the same as the one working. Is there some cache somewhere that I should remove?

In the logs I see this:

time="2023-07-03T19:36:37Z" level=debug msg="'504 Gateway Timeout' caused by: dial tcp 10.0.0.14:8081: i/o timeout"

But in portainer, if I check my home-stack_default network, it says 10.0.3.0/24, so I guess this ip (10.0.0.14) is not the proper one?

Hum, I just found the solution:

If I now force traefik to use the default network:
- "--providers.docker.network=home-stack_default"

it does work. But if somebody could explain why it started to use another network and how it decided to stick with it, I would gladly take its explanations

I recommend to use a dedicated Docker network, not rely on Docker default networks, see simple Traefik example.
