Description
Not sure if this is a traefik issue or a dockersocket issue but traefik stops working after upgrade to v3.6.0 with the following error
2025-11-14T18:33:37+11:00 ERR Failed to create Docker API client error="unable to parse docker host `dockersocket`" providerName=docker

Research direction
Start by reproducing the Docker socket connection failure with Traefik v3.6.0 and the docker-socket-proxy setup. Read the Docker provider error about parsing the dockersocket host and compare the proxy configuration with the expected Docker host format. Done means Traefik connects successfully through the proxy without repeated provider errors.
