Docker 29.0 and Traefik Compatibility: The API Version Mismatch
After upgrading to Docker 29.0, my entire Traefik setup suddenly stopped working, even the latest Traefik version failed to connect. The root cause turned out to be a breaking API change: Docker 29 now requires API 1.44+, while Traefik still uses 1.24. Until Traefik updates its Docker client, the only fix is to downgrade to Docker 28.5.2 and hold updates.
