Change in dynamic config for a TCP router applied but effectively ignored about traefik HOT 3 CLOSED

Hello @aspnetde 👋
I've tried reproducing the issue but everything seems to work as expected.

Here is my setup:

./docker-compose.yaml:

version: '3.8'

services:
  traefik:
    image: traefik:v2.10
    restart: always
    command:
      - --api.insecure=true
      - --log.level=debug
      - --providers.docker=true
      - --providers.docker.exposedbydefault=false
      - --providers.file.directory=/config
      - --providers.file.watch=true
      - --entrypoints.websecure.address=:443
    ports:
      - 443:443
      - 8080:8080
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./config:/config

config/routers.yaml

tcp:
  routers:
    external-service-router:
      rule: "HostSNI(`*`)"
      service: "external-service"
      entryPoints: ["websecure"]
  services:
    external-service:
      loadBalancer:
        servers:
          - address: "<IP_A>:443"

The IP I used are those of public server such as traefik.io.
When I change the IP address to something else, I see the right log:

Creating TCP server 0 at :443" serverName=0 entryPointName=websecure routerName=external-service-router@file serviceName=external-service

I call the service by doing a curl as follow:

curl https://localhost -H "Host: traefik.io" -vk

Could you provide a self contained reproducible test case? Or point me where my setup differs?

Unfortunately, I don't have a development machine available right now. Your configuration looks quite similar to mine as posted above, but it's not exactly the same. Maybe disabling the debug mode would have the (not so) desired effect? Anyway, I can try to reproduce it once again in a couple of days.

@jspdown You are right, I can reproduce the correct behavior now, too. Even when testing it with my config, without using the debug mode. I have no idea what went wrong back initially.
