Docker Update 4.56 and onwards issues with traefik:v2.5.3-windowsservercore-1809

adinesen · February 16, 2026, 3:13pm

Hi, Since around 4.56.0 and any newer versions myTraefik container has stopped working and therefore my other containers can no longer connect to each other and the sitecore 10.3 xm toplogy setup that I am using no longer works. I get the following errors in the logs on the Traefik container:

level=error msg="Provider connection error Error response from daemon: , retyring in (random time in seconds)" ProviderName=docker
level=error msg="Failed to retrieve information of the docker client and server host: Error response from daemon: " providerName=docker

some Env details:
COMPOSE_PROJECT_NAME=sitecore-xm1
COMPOSE_PROJECT_VERSION=1.0.0
SITECORE_DOCKER_REGISTRY=scr.sitecore.com/sxp/
SITECORE_DOCKER_MODULES_REGISTRY=scr.sitecore.com/sxp/modules/
SITECORE_TOOLS_REGISTRY=scr.sitecore.com/tools/
TOOLS_VERSION=10.2-1809
SITECORE_VERSION=10.3.0-ltsc2019
SITECORE_ASSETS_VERSION=6.4-1809
HEADLESS_SERVICES_VERSION=21.0.583-1809
MANAGEMENT_SERVICES_VERSION=5.1-1809
EXTERNAL_IMAGE_TAG_SUFFIX=ltsc2019
TRAEFIK_IMAGE=traefik:v2.5.3-windowsservercore-1809
TRAEFIK_ISOLATION=hyperv
ISOLATION=default

If I revert to an older version like 4.44.0 then it works fine again. Can anyone assist on how I would resolve this?

Thanks

There is no Docker 4.56, maybe you mean Docker Desktop 4.56. Make sure to update Docker and Traefik, as API for discovering services has changed, and you need both with the latest version.

adinesen · February 16, 2026, 3:19pm

Thanks. Yes I meant Docker Desktop. What version of Traefik would I use for Docker Desktop 4.56+ given I am currently using traefik:v2.5.3-windowsservercore-1809?

adinesen · February 16, 2026, 3:29pm

If I updated to traefik:v3.4.1-windowsservercore-1809, can I assume this would still work and with the v3 are there any new configurations I would need to consider:

services:
traefik:
isolation: ${TRAEFIK_ISOLATION}
image: ${TRAEFIK_IMAGE}
command:

"--ping"
"--api.insecure=true"
"--providers.docker.endpoint=npipe:////./pipe/docker_engine"
"--providers.docker.exposedByDefault=false"
"--providers.file.directory=C:/etc/traefik/config/dynamic"
"--entryPoints.websecure.address=:443"
"--entryPoints.websecure.forwardedHeaders.insecure"

So I have updated to Docker Desktop 4.60.1 and traefik:v3.4.1-windowsservercore-1809 and I still get the same issue:

2026-02-16T15:58:43Z ERR Failed to retrieve information of the docker client and server host error="Error response from daemon: " providerName=docker

2026-02-16T15:58:43Z ERR Provider error, retrying in 3.149567805s error="Error response from daemon: " providerName=docker

Check Traefik releases (link) and Traefik container images (link).

adinesen · February 17, 2026, 9:50am

Thanks but I have already tried the newest windowsservercore-1809 version? Am I just suppose to try different ones until something works?

bluepuma77 · February 17, 2026, 12:32pm

Just search the hub for latest windows image (link), which is v3.6.8-windowsservercore-ltsc2022.

It seems "Windows Server 2019" ("1809") is not supported anymore. You would need to downgrade Docker Desktop to a version with Docker Engine < v29 for the old Traefik version to continue to work.

adinesen · February 17, 2026, 4:44pm

OK. So I have downloaded and added traefik:v3.6.8-windowsservercore-ltsc2022

This also I assume means I need to change my env file for ltsc2022 for my sitecore 10.3.0 docker environment. So I followed this short guide:

Updated env:

TOOLS_VERSION=10.2-1809
SITECORE_VERSION=10.3.0-ltsc2022
SITECORE_ASSETS_VERSION=6.4-1809
HEADLESS_SERVICES_VERSION=21.0.583-1809
MANAGEMENT_SERVICES_VERSION=5.1-1809
EXTERNAL_IMAGE_TAG_SUFFIX=ltsc2022

TRAEFIK_IMAGE=traefik:v3.6.8-windowsservercore-ltsc2022
TRAEFIK_ISOLATION=hyperv
ISOLATION=process

Now everything is spinning up again but I still get 404 page when I try and hit one of my server containers. Looking at the Traefik logs I now see this:

2026-02-17T16:39:00Z ERR error="service \"cm-sitecore-xm1\" error: port is missing" container=cm-sitecore-xm1-04dcfd403936428aeacfb2e421d39fc3bac17e939b8fe5f7b4b09c0c9d0df01b providerName=docker

So is there some additional configuration I am missing here?

bluepuma77 · February 18, 2026, 5:45am

seems the internal port for a service needs to be specified. Maybe the target services used EXPOSE before to indicate which port to use.

  whoami:
    image: traefik/whoami:v1.11
    networks:
      - proxy
    labels:
      - traefik.enable=true
      - traefik.http.routers.mywhoami.rule=Host(`whoami.example.com`)
      - traefik.http.services.mywhoami.loadbalancer.server.port=80

adinesen · February 18, 2026, 9:37am

I havent changed these configurations so EXPOSE hasnt been removed if that is what you mean?

how would I go about updating the config given they are effectively web servers served over https/ http?

As an example for my CM container instance I have added networks:proxy and the loadbalancer.server.port (at the bottom) for port 80, or should it be for 443 as I want to serve on https?

adinesen · February 18, 2026, 10:32am

Nevermind. I think I have it working now just by adding the server port setting to my container instances on the traefik network. Will test it further now it looks like it is working. Thanks
