  * Creating separate, named configurations by using `+quarkus.tls.<name>.*+`.
 By specifying the `+quarkus.tls.<name>.*+` properties, you can adapt the TLS settings for a specific component.

+====
+The default TLS configuration is not a fallback/global configuration. This means that each named TLS configuration
+(or "TLS bucket") needs to provide its own properties. For instance, `quarkus.tls.reload-period` will only be applied

 === Configuring HTTPS for a HTTP server
 
 To ensure secure client-server communication, the client is often required to verify the server's authenticity.

 == Reloading certificates
 
 The `TlsConfiguration` obtained from the `TLSConfigurationRegistry` includes a mechanism for reloading certificates.
-The `reload` method refreshes the keystores and truststores, typically by reloading them from the file system.
