If no valid certificate is found, Traefik Proxy serves a default auto-signed certificate. Deploy traefik and a couple of services, some with http routers and others with tcp routers & tls passthrough using a different subdomain per service. Mail server handles his own tls servers so a tls passthrough seems logical. Instead, we plan to implement something similar to what can be done with Nginx. This means we dont want Traefik intercepting and instead letting the communications with the outside world (and Lets Encrypt) continue through to the VM. I currently have a Traefik instance that's being run using the following. Do you want to serve TLS with a self-signed certificate?
