No servers available when routing

[pgm-rookie]

My route definition code is like below:

@Configuration
public class RouteConfiguration {`
@Bean`
public RouteLocator routeLocator(RouteLocatorBuilder builder){
    return builder.routes()
             .route("user-management", r -> r
                    .path("/user-management/**")
                    .filters(f -> f
                                    .hystrix(h->  h.setName("fallbackCmd").setFallbackUri("forward:/fallback"))                             
                    )
                    .uri("lb://user-management"))
            .build();
    }
}

I start eureka server,config center,gateway in order,and then i start user management service. Requests can not route to user management service,

o.s.c.l.core.RoundRobinLoadBalancer      : No servers available for service: USER-MANAGEMENT

This log will appear in gateway log file,but if i restart gateway ,it will be OK. I remembered this problem does not appear in SpringCloud version:Finchley, i can start gateway before other downstream services or after.

How i can relsove this problem, THKS!

How long did you wait?

[pgm-rookie]

until I restart gateway service or requests can not route to downstream service , if I change property "spring.cloud.netflix.ribbon=true" to ues ribbon instead of spring cloud loadbalance, there's no problem.

It may have something to do with spring cloud loadbalance.

Can you provide a complete, minimal, verifiable sample that reproduces the problem? It should be available as a GitHub (or similar) project or attached to this issue as a zip file.

I have the same problem, It's sad that up to now, the spring cloud team can't provide a walkaround. I try to re-route to the actual service but not fruitful. The gateway logs keep saying, No servers availble for service customer

@kisevu did you find solution for it? im have no idea what is causing that.

Earlier on, it was a dependency issue and issues about the spring boot version. Try and use spring boot 3.2.1 or 3.1.7 with java 17 or higher and this can mitigate the issue. I nolonger face the same issue. Also try and use tomcat 9 >
