Opencloud crashes with Docker Update 29.0

After the upgrade of docker to 29.0.0 on my Debian System Opencloud stopped working.

After some fiddling with logfiles the root cause was Traefik has Problems with this Docker version. It throws:

"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"

A quick Websearch (without using AI) provides a link to this thread on traefiklabs:
https://community.traefik.io/t/traefik-stops-working-it-uses-old-api-version-1-24/29019

There are a few suggestions to remedy the problem. The solution from Vasilii that worked for me, was to put a file named daemon.json in /etc/docker/. This file didn't exist on my installation. Take care if you already have this file. The content, that should be in there is

{ "min-api-version": "1.24" }

After a complete docker restart, everything worked again.
