Traefik container fails with "client version 1.24 is too old" on a fresh installation

[n-gon]

To Reproduce

Hello Dokploy Team,

I have a new Dokploy installation on a Hetzner VM running Ubuntu 24.04. The Traefik container is continuously failing to connect to the Docker provider, making all my applications inaccessible. The Traefik logs repeatedly show the error: Provider 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"

This is happening despite the fact that the system is using a very modern version of Traefik.

Current vs. Expected behavior

Troubleshooting steps (all have failed):

• Confirmed traefik:v3.5.0 is running, which should be compatible with modern Docker APIs.

• The main config file at /etc/dokploy/traefik/traefik.yml does not contain any clientVersion directive. Its contents are:

global:
sendAnonymousUsage: false
providers:
swarm:
exposedByDefault: false
watch: true
docker:
exposedByDefault: false
watch: true
network: dokploy-network
file:
directory: /etc/dokploy/traefik/dynamic
watch: true
entryPoints:
web:
address: :80
websecure:
address: :443
http3:
advertisedPort: 443

• A recursive search for clientVersion in the /etc/dokploy/traefik/dynamic directory returned no results. The directive is not present there.

• docker inspect revealed that the container was not started by Docker Compose (the com.docker.compose.project.config_files label is empty).

• Stopped and removed the original dokploy-traefik container and manually launched a new one with a clean docker run command, explicitly omitting any version flags.

sudo docker run -d
--name dokploy-traefik
--restart unless-stopped
-p 80:80 -p 443:443 -p 8080:8080 -p 443:443/udp
-v /etc/dokploy/traefik/traefik.yml:/etc/traefik/traefik.yml
-v /etc/dokploy/traefik/dynamic:/etc/dokploy/traefik/dynamic
-v /var/run/docker.sock:/var/run/docker.sock
--network dokploy-network
traefik:v3.5.0

Provide environment information

Server: Hetzner Cloud VP
OS: Ubuntu 24.04.3 LTS
Dokploy version: dokploy/dokploy:latest
Traefik image: traefik:v3.5.0

You're right @n-gon, a few minutes ago I also started getting this error on the new machine.

The error occurred with both docker and swarm providers, causing continuous retry attempts.

Upgrading to the latest Traefik image resolved the issue:

Stop and remove the existing container

docker stop dokploy-traefik && docker rm dokploy-traefik

Pull the latest Traefik image

docker pull traefik:latest

Recreate the container with the latest image

docker run -d \
  --name dokploy-traefik \
  --restart always \
  -v /etc/dokploy/traefik/dynamic:/etc/dokploy/traefik/dynamic \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v /etc/dokploy/traefik/traefik.yml:/etc/traefik/traefik.yml \
  -p 80:80 \
  -p 443:443 \
  -p 8080:8080 \
  --network dokploy-network \
  traefik:latest

Hope this gets fixed ASAP.

I also tried to locate the install.sh source in this GitHub repo, but couldn’t find it, so I wasn’t able to open a PR for it.

However, updating the Traefik image from v3.5.0 to v3.6.1 on the server side fixes the issue for me.

docker run -d \
        --name dokploy-traefik \
        --restart always \
        -v /etc/dokploy/traefik/traefik.yml:/etc/traefik/traefik.yml \
        -v /etc/dokploy/traefik/dynamic:/etc/dokploy/traefik/dynamic \
        -v /var/run/docker.sock:/var/run/docker.sock \
        -p 80:80/tcp \
        -p 443:443/tcp \
        -p 443:443/udp \
        traefik:v3.6.1 

@MasterLambaster thanks!

docker network connect dokploy-network dokploy-traefik

@cagdaskarademir you have network bit missing

Ran into the same issue here installing latest dokploy yesterday.

Also discussed here: https://community.traefik.io/t/traefik-stops-working-it-uses-old-api-version-1-24/29019/13

Hope this gets fixed asap.
