server.port=9101
spring.cloud.config.server.git.uri=https://github.com/cambyze/cambyze-properties.git
spring.cloud.config.server.git.username=cambyze-public

Answer 1

The problem was that the default branch created by default is main and not master.

To fix it, my new application.properties to force the default-label to "main"

spring.application.name=config-server

server.port=9101
spring.cloud.config.server.git.uri=https://github.com/cambyze/cambyze-properties.git
spring.cloud.config.server.git.username=cambyze-public
spring.cloud.config.server.git.password=CambyzePublic2020
spring.cloud.config.server.git.clone-on-start=true
spring.cloud.config.server.git.default-label=main
