Sometimes, especially when deploying following a Zero Trust security model, you want Traefik Proxy to verify that clients accessing the services are authorized beforehand, instead of having them authorized by default.

The certificatesresolvers specify details about the Let's Encrypt account, Let's Encrypt challenge, Let's Encrypt servers, and the certificate storage. HTTP/3 is running on the VM. Traefik generates these certificates when it starts. In this case a slash is added to siteexample.io/portainer and redirect to siteexample.io/portainer/. Please have a look at the UDP routers, Host SNI is not needed, because basically speaking UDP does not have SNI. Setting the scheme explicitly (http/https/h2c), Configuring the name of the kubernetes service port to start with https (https), Setting the kubernetes service port to use port 443 (https), on both sides, you'll be warned if the ports don't match, and the.
