Traefik version image v2.10.6 no longer supported on current stable docker image (29.2.1)

[manocho]

I have cloned and installed a new setup of OpenIAP and I'm getting an error when traefik starts:

time="2026-03-01T18:31:12Z" level=error msg="Provider connection error Error response from daemon: client version 1.24 is too old. Minimum supported API version is 1.44, please upgrade your client to a newer version, retrying in 425.975217ms" providerName=docker

I'm using debian-13.3.0-amd64 with docker official APT stable source: https://download.docker.com/linux/debian

Changing traefik to 2.11 resolves the issue but I don't know what version should be the right one to suggest:

Original docker-compose.yml

services:
  traefik:
    image: traefik:v2.10.6
...

Thank you very much

The main reason we “locked in” Traefik at tag v2.10.6 was that Traefik fundamentally changed how it handles open sockets, which caused clients to get disconnected constantly.

According to their documentation, using the settings below should fix it, but in my testing it did not. So I pinned Traefik to a working version and decided to look at it later, when Traefik has matured the change to something that works with gRPC. I have to admit, I forgot to come back and look at it.

# Timeout settings for gRPC
- "--entrypoints.web.transport.respondingTimeouts.readTimeout=90000s"
- "--entrypoints.web.transport.respondingTimeouts.writeTimeout=90000s"
- "--entrypoints.web.transport.lifeCycle.requestAcceptGraceTimeout=90000s"

To the best of my knowledge, there should not be any issues updating to a newer version of Traefik as long as it is in the 2.x range. But as you can see, it has not been tested. If you also experience issues with gRPC clients getting disconnected all the time, try adjusting the settings above and see if it solves it. If it does, I would appreciate a heads up in this thread so I can update the Docker Compose files and documentation.
