How to configure maintenance page in Traefik v1.7.33

We are using Traefik V1.7.33 as Azure ServiceFabric Application, which will perform traffic redirection to the windows containers in VMSS. We need to redirect traffic to the maintenance web page when there is an container image refresh. Following TOML configuration change didn't help.

[http.middlewares] [http.middlewares.test-errorpage.errors] status = ["500-599"] service = "serviceError" query = "/{status}.html"

[frontends] [] backend = "website" [] [] status = ["500-599"] backend = "error" query = "/{status}.html" [] rule = "Host:"

Would like to know is there any other way to perform this.
