FIXED Spring Cloud Gateway | No servers available for service: ms-authentication-server

Question

I'm facing this issue, I'm running a few microservices in my local machine but when I try to use gateway server I got this:

No servers available for service: ms-authentication-server

In my gateway server configuration I have:

pom.xml `

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-webflux</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-gateway</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        <version>4.1.0</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>       
</dependencies>

`

application.yml

server:
  port: 8085
spring:
  application:
    name: ms-gateway-server
  cloud:
    gateway:
      routes:
        - id: ms-authentication-server
          uri: lb://ms-authentication-server
          predicates:
            - Path=/api/v1/**
          filters:
            - StripPrefix=2
    loadbalancer:
      ribbon:
        enabled: false

eureka:
  client:
    registerWithEureka: true
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
  instance:
    preferIpAddress: true
    leaseRenewalIntervalInSeconds: 10
    leaseExpirationDurationInSeconds: 30

My eureka server looks like this: Eureka server

The ms-authentication-server is working when I use its url direcly, but across gateway server It's not working.

I tried changing microservice name (lb://microservice) and use http://localhost... instead, and It's working.

I'm using:

1. Spring Boot 3.2.1
2. Spring cloud 4.1.0 (2023.0.0)

Eureka console is showing nothing related to this error.

FIX Problem was that I was trying to connect a microservice which is using context path, I update that part and It works.
