Hello @wiliiwin Where/what file did you define this in? How did you include it in your traefik instance? ---

Hi @wiliiwin You only define a static config file in your docker run command. Middlewares are defined in dynamic configuration. If this middleware is defined in traefik.yml it will not work. You would need to create a file provider and put this definition in that file. > **[Configuration Introduction - Traefik](https://docs.traefik.io/getting-started/configuration-overview/)** > **[File - Traefik](https://docs.traefik.io/providers/file/)** ---

As you are defining it in a file provider and using it in another provider set it as latency-check@file. ---
