Spring Cloud Docker - Cannot access any service through api gateway and Cannot access any service itself

I have a problem about accessing any service through api gateway.
Here is the properties file of api-gateway
```

eureka.client.serviceUrl.defaultZone=http://eurekaserver:8761/eureka/
spring.application.name=api-gateway

server.port=8600

## User Service Route
spring.cloud.gateway.routes[0].id=user-service
spring.cloud.gateway.routes[0].uri=lb://user-service
spring.cloud.gateway.routes[0].predicates[0]=Path=/userservice-api/**

## Advertisement Service Route
spring.cloud.gateway.routes[1].id=advertisement-service
spring.cloud.gateway.routes[1].uri=lb://advertisement-service
spring.cloud.gateway.routes[1].predicates[0]=Path=/advertisementservice-api/**

## Management Service Route
spring.cloud.gateway.routes[2].id=management-service
spring.cloud.gateway.routes[2].uri=lb://management-service
spring.cloud.gateway.routes[2].predicates[0]=Path=/managementservice-api/**

## Report Service Route
spring.cloud.gateway.routes[3].id=report-service
spring.cloud.gateway.routes[3].uri=lb://report-service
spring.cloud.gateway.routes[3].predicates[0]=Path=/reportservice-api/**

```
For instance, I tried to access user service through api gateway, I defined the url shown below.
```

http://api-gateway:8600/userservice-api/api/v1/users/signup

```
It didn't work (I only saw Could not send request).

I also defined some urls shown below for this purpose but all these cannot work.
```

http://localhost:8600/userservice-api/api/v1/users/signup

http://localhost:8600/user-service/api/v1/users/signup

http://api-gateway:8600/userservice-api/api/v1/users/signup

http://api-gateway:8600/user-service/api/v1/users/signup

```

I used these urls shown below but nothing changed. I still got the same error.

http://gatewayserver:8600/userservice-api/api/v1/users/signup

http://gatewayserver:8600/user-service/api/v1/users/signup

How can I fix it ?
