Traefik config doesn't work

[LovesTha]

Describe the bug
Doing the config for k3s behind a reverse proxy, creating /var/lib/rancher/k3s/server/manifests/traefik-config.yaml does nothing to which ports traefik was binding to.

I noticed /var/lib/rancher/k3s/server/manifests/traefik.yaml exists, but merging the suggested config into that file also did nothing.

To Reproduce
Steps to reproduce the behaviour:

1. Follow instructions for Using an existing reverse proxy
2. Output of kubectl get svc -n kube-system | grep traefik is still ports 80 & 443

NB: traefik service in that output indicates it hasn't been restarted, the uptime is large, but so is the uptime in the example output.

Expected behaviour
Traefik is reloaded with customised exposed ports

Hello,

I tried again on a local VM and it works just fine :

[arch@archlinux ~]$  kubectl get svc/traefik -n kube-system
NAME      TYPE           CLUSTER-IP    EXTERNAL-IP       PORT(S)                      AGE
traefik   LoadBalancer   10.43.66.56   192.168.200.251   80:30356/TCP,443:32320/TCP   34s
[arch@archlinux ~]$ sudo vim /var/lib/rancher/k3s/server/manifests/traefik-config.yaml
[arch@archlinux ~]$  kubectl get svc/traefik -n kube-system -w
NAME      TYPE           CLUSTER-IP    EXTERNAL-IP       PORT(S)                      AGE
traefik   LoadBalancer   10.43.66.56   192.168.200.251   80:30356/TCP,443:32320/TCP   65s
traefik   LoadBalancer   10.43.66.56   192.168.200.251,192.168.200.251   8080:30356/TCP,8443:32320/TCP   71s

There might be something wrong in what you re doing maybe?

Happened for me too, started googling, found this issue, went back to open it again just to check, it started working without any changes. Delay on config change?
