Spring Cloud Config Remote - USERAUTH fail - spring

Question

I'm trying to do a ConfigServer with a remote repository.
The ConfigServer pom's file is:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-server</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bus-amqp</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-monitor</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
Inthe the properties file, i have the url, user and password of the repository. Is necessary anything else?. The file is like:
server.port:8888
spring.cloud.config.server.git.uri:git#gitlab.com:user/repo.git
spring.cloud.config.server.git.uri.username:user
spring.cloud.config.server.git.uri.password:password
spring.profiles.active:config-monitor
rabbitmq.host:rabbitmq
rabbitmq.port:5672
rabbitmq.username:guest
rabbitmq.password:guest
spring.cloud.bus.enabled:true
spring.cloud.config.server.monitor.gitlab.enabled:true
And I created a Webhook in gitLab with url http://localhost:8888/monitor too.
But when a client try to start, the ConfigServer's console shows:
**2017-03-14 23:46:35.767 ERROR 10595 --- [nio-8888-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.IllegalStateException: Cannot clone or checkout repository] with root cause

Dou you know how can i resolver it?
