Spring Cloud Config Server - Git - Not authorized

I have a Spring-Boot application that use Spring Cloud Config and I'm trying to get the application's configuration file from Bitbucket. I was able to get the configuration file some time ago but now I'm getting an error when I try to access by config-server url.

application.yml:

server:
    port: 8888
spring:
    application:
        name: config-server
    cloud:
        config:
            server:
                git:
                    password: ##########
                    username: ##########
                    uri: https://USERNAME@bitbucket.org/repositorios-closeup/cup-configuration-files
                    searchPaths: '{application}'

When I try to access the url the application is showing an error - NOT AUTHORIZED:

org.eclipse.jgit.api.errors.TransportException: https://USERNAME@bitbucket.org/repositorios-closeup/cup-configuration-files: not authorized

Does anybody know what is happening? I've already check all credentials and url on bitbucket.

Generate a token(classic) from developer settings in your GitHub Settings.Use that as a password and you'll be okay
