traefik: Traefik doesn't auto re-add re-enabled service based on Consul Catalog changes

Do you want to request a feature or report a bug?

Bug

What did you do?

• register service -> service comes available in traefik
• stop service -> service is gone from traefik
• start same service -> service is not available in traefik but alive in Consul
• wait 5-20 minutes -> service is not available in traefik
• restart traefik -> service comes available in traefik

What did you expect to see?

It seems to be a sub-issue of previously closed issue

What did you see instead?

Changes are properly updated, but in case of deregistering and registering same service there are issues.

Also I believe I could misconfigured something, would appreciate for hints

Output of traefik version: (What version of Traefik are you using?)

    compress = false
    [entryPoints.http.proxyProtocol]
        trustedIPs = ["10.0.0.0/8"]
  [entryPoints.traefik_api]
    address = ":1111"
    compress = false
    
[ping]
  entryPoint = "http"

[consulCatalog]
endpoint = "127.0.0.1:8450"
exposedByDefault = false
prefix = "traefik"

[api]
  entryPoint = "traefik_api"
  dashboard = true
  debug = true
[traefikLog]
  format   = "json"
