How can I use the logback.xml stored in the Azure Spring Cloud Config Server?

Hi,

I want to store the logback.xml in the Azure Spring Cloud Config Server.

I have set up a repo with the application.properties and the logback.xml.

All the properties in the application.properties can be fetched, but the property logging.config gets a 401 Unauthorized.

This is how the property is set in the application.properties:

logging.config=${spring.cloud.config.uri}/application/default/master/logback.xml

This is the error:

My understanding is that I should supply the credentials, but how?
Where I can see the credentials defined in the Azure Config Server?
