I'm using Kubernetes in Google Cloud Platform. I configured a cluster with Traefik with SSL and Lets Encrypt, it works well, then I changed a little setting in [acme] and I start receiving this error after kubectl apply -f .: TRAEFIK DEFAULT CERT.

I already rollback the file settings, but I continue to receive this error (with previous configurations).

It's normal?

I just need to wait because Letsencrypt need time? For how long time?

Thanks.
