404 Page Not Found

Describe the problem/error/question

As of yesterday my VPS hosted N8N instance started returning a 404 page not found error. The SSL certificate is TRAEFIK DEFAULT CERT rather than a lets encrypt certificate. My workflows were still running as i was getting my normal scheduled telegram messages etc.

I carried out some troubleshooting and have been seeing the below errors:
2025-11-11T15:43:34Z ERR Provider error, retrying in 1.468570889s 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 tried updating the compose.yml file to include:
image: “traefik:latest”

Which updated traefik but the issue remained.

Hoping this was just a bug with my instance i backed up everything, reinstalled the OS and ran through the setup process but immediately im seeing the same errors, although this time i havent updated traefik as per the above.

Anyone have any ideas whats happening? Im guessing something has updated which is causing incompatibility somewhere?

What is the error message (if any)?

I received the same error yesterday after upgrading the OS.. Appears traefik is noi ready for the newer release of dockers being installed by the OS upgrade… I restored the most recent snapshot (One prior to upgrading the OS) to recover

Thanks, i downgraded Docker and it came back up.

For anyone else with the same issue below are the commands i ran on Ubuntu to downgrade Docker, with help from ChatGPT.

:one: Stop Docker

sudo systemctl stop docker

:two: Remove current Docker packages

sudo apt remove -y docker-ce docker-ce-cli containerd.io
sudo apt purge -y docker-ce docker-ce-cli containerd.io

:warning: Optional: If you want a completely clean install, remove Docker data (containers, volumes, images). Only do this if you’ve backed up anything important:

sudo rm -rf /var/lib/docker

:three: Install the specific version

sudo apt update
sudo apt install -y docker-ce=5:26.1.3-1~ubuntu.22.04~jammy \
                    docker-ce-cli=5:26.1.3-1~ubuntu.22.04~jammy \
                    containerd.io

:four: Prevent automatic upgrades

sudo apt-mark hold docker-ce docker-ce-cli containerd.io

:five: Start Docker

sudo systemctl start docker
sudo systemctl enable docker

:six: Verify Docker version

docker version

I did something a little different, similar: Here is the script I wrote:
Here is the OS Info:
lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 24.04.3 LTS
Release: 24.04
Codename: noble

Beginning of script next line:::

echo “Output being sent to ${OUTPUT_FILE}”

echo “========================================” > $OUTPUT_FILE
echo “DOCKER FREEZE LOG - $DATE” >> $OUTPUT_FILE
echo “========================================” >> $OUTPUT_FILE

lsb_release -a >> $OUTPUT_FILE

echo “” >> $OUTPUT_FILE
echo “— Docker Binary Version —” >> $OUTPUT_FILE
docker --version >> $OUTPUT_FILE

}
