Summary
Traefik is an HTTP reverse proxy and load balancer. Prior to version 2.6.1, Traefik skips the router transport layer security (TLS) configuration when the host header is a fully qualified domain name (FQDN). For a request, the TLS configuration choice can be different than the router choice, which implies the use of a wrong TLS configuration. When sending a request using FQDN handled by a router configured with a dedicated TLS configuration, the TLS configuration falls back to the default configuration that might not correspond to the configured one. If the CNAME flattening is enabled, the selected TLS configuration is the SNI one and the routing uses the CNAME value, so this can skip the expected TLS configuration. Version 2.6.1 contains a patch for this issue. As a workaround, one may add the FDQN to the host rule. However, there is no workaround if the CNAME flattening is enabled.

         value: "Traefik es un proxy inverso HTTP y equilibrador de carga. En versiones anteriores a 2.6.1, Traefik omitía la configuración de seguridad de la capa de transporte (TLS) del router cuando el encabezado del host era un nombre de dominio completo (FQDN). Para una petición, la elección de la configuración TLS puede ser diferente a la elección del router, lo que implica el uso de una configuración TLS errónea. Cuando es enviada una petición usando FQDN manejada por un router configurado con una configuración TLS dedicada, la configuración TLS vuelve a la configuración por defecto que puede no corresponder a la configurada. Si el aplanamiento de CNAME está habilitado, la configuración TLS seleccionada es la de SNI y el enrutamiento usa el valor de CNAME, por lo que puede omitir la configuración TLS esperada. La versión 2.6.1 contiene un parche para este problema. Como medida de mitigación, puede añadirse el FDQN a la regla de host. Sin embargo, no es presentada una medida de mitigación si el aplanamiento CNAME está habilitado",
