[Bug]: Coolify Traefik Proxy No Longer Working After Recent Update

[NoorChasib]

Error Message and Logs

I am getting an odd issue ever since updating packages and rebooting my server. The coolify proxy is no longer working and when I try to access a page for one of my applications, I get no available server. Coolify still works but not other apps.

When checking the traefik proxy logs, all I see is:

2025-11-11T01:30:45.152362608Z 2025-11-11T01:30:45Z ERR Provider error, retrying in 3.147624984s 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" providerName=docker

For reference here is my traefik proxy config:

I have tried switching to Caddy, which works for some of my applications but not others.

Not sure what the issue is and what I can do to fix this, so if anyone has any suggestions I would greatly appreciate it!

Same issue here

Same here after updating packages on my linux server.It was a docker cd packages update.I think they broke something.Let's hope they fixed it soon.I'm using traefik too for reverse proxy.I don't know where is the problem,on the docker or in the traefik.

I've got the same error in traefik logs:

2025-11-11T08:26:54+02:00 ERR Provider error, retrying in 2.637428756s 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" providerName=docker

I have the same issue.

[thefeli73]

same here, for me it seems to be an (automatic) update to docker 29 this night that raised the MinAPI to 1.44.

Reverting to docker 28 fixed the issue for me.
On Rocky 9 this can be done like this

dnf install -y \
  docker-ce-3:28.5.2-1.el9 \
  docker-ce-cli-1:28.5.2-1.el9 \
  containerd.io-1.7.28-2.el9 \
  --allowerasing

and disable dnf-automatic for now:

systemctl disable dnf-automatic-install.timer
systemctl stop dnf-automatic-install.timer

Collify should be made to use a more recent docker API version ASAP
This is an issue with Traefik using an ancient docker client so not much coolify can do it seems

[codewarriordo]

Same on debian with treafik latest image.
I only makes my weekly sudo apt update an nothinh works anymore.
Who will fix it? The docker guys or the treafik guys?

[ckerfurt]

Same issue here — started after the latest Traefik / Docker updates last night.

We’re running a standalone setup (no Coolify) with
Traefik v2.11.29
Docker Engine 27.3.1 (API min 1.44)
Compose v2.29.7
on Debian 13.

Since the update, Traefik fails to connect to the Docker provider with:
Failed to retrieve information of the docker client and server host: 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

No DOCKER_API_VERSION is set anywhere.
Even explicitly setting DOCKER_API_VERSION=1.44 in the compose file doesn’t change the behavior — Traefik still tries to use /v1.24 on the socket.

I have the same problem with Traefik and Watchtower. I think the problem is probably due to Docker and not Traefik.

Same issue here with traefik and docker.

[bjarneo]

Ubuntu 24.04 noble:

systemctl stop docker
apt install -y docker-ce=5:28.5.2-1~ubuntu.24.04~noble docker-ce-cli=5:28.5.2-1~ubuntu.24.04~noble containerd.io --allow-downgrades
systemctl start docker

Solved it for me. Turned off auto updates I have added to a cron job.

[timble-one]

After doing @bjarneo 's command, one can use apt-mark hold to stop auto-updating temporarily:
sudo apt-mark hold docker-ce docker-ce-cli containerd.io

[mfg92]

I have adapted the solution provided by @bjarneo (which is for Ubuntu 24.04 aka noble) for Ubuntu 22.04 aka jammy:

systemctl stop docker
apt install -y docker-ce=5:28.5.2-1~ubuntu.22.04~jammy docker-ce-cli=5:28.5.2-1~ubuntu.22.04~jammy containerd.io --allow-downgrades
systemctl start docker

It worked for me perfectly.
