Getting "Gateway Timeout" error when using Zuul proxy server

Getting "Gateway Timeout" error when using Zuul proxy server - spring-boot

I am developing spring boot microservices for my project. I am using Zuul as a proxy server. However when I route the api calls always I am getting Gateway Timeout or Internal Server errors. I am also use feign client to call external api. When I do that, always following response is thrown:
response
{
"timestamp": "2019-08-16T10:10:10.128+0000",
"status": 504,
"error": "Gateway Timeout",
"message": "com.netflix.zuul.exception.ZuulException: Hystrix Readed time out"
}
I use docker to rum my microservices. And when I see the logs of zuul proxy server it look as follows:

Using Zuul with Eureka server throws com.netflix.zuul.exception.ZuulException: Forwarding error

I have simple microservice app contains:
eureka-server
search-service
zuul-getway
both zuul-getway and search-serviceappear on eureka-server.
I don't know if it helps to know that I'm using Java-11 because most of the solutions were using Java-1.8. and I am using Xampp.
This error has been repeated a lot on GitHub and I have tried most of the solutions presented, but this error still appears every time.
This error appear with all requests:

As my guess was right (see comments), I'll leave it here as answer:
From the stacktraces
Caused by: java.lang.RuntimeException: org.apache.http.conn.ConnectTimeoutException: Connect
to prof1.com:8401 [prof1.com/3.223.115.185] failed: connect timed out
it seems for whatever reason you are trying to connect to prof1.com on port 8401. If you haven't manipulated your HOSTS-File to alias this domain, imho that can't work because prof1.com seems to be in the hands of a domain seller atm. (or you are actually the seller ;-) ) - so there seems to be some misconfiguration.
Try setting the domain to an existing one under your control and it should work.
A bit of general advice: Reading stacktraces (the whole one) almost always reveals the problem, so fight through it and be open for the words, they don't judge, they just show you your assumptions of what your code/config does might be wrong. That's not a fault, that's just reality.

Zuul Forwarding error, Load balancer does not have available server for client

I'm trying to follow this tutorial : Spring Boot Micro-Services with Eureka and Zuul proxy with Feign Client.
I created 3 microservices : An Api Gateway with Zuul, a resource Service with Feign, a Discovery Service with Eureka and another microservice PRIMO USER MANAGEMENT SERVICE that contains some business logic for my front end application.
I'm facing an error "Forwarding error" while trying to invoke a URL from the API Gateway : http://localhost:8662/primo-user-management-service/api/auth/getOffersa
while it works when i invoke it directly from my microservice "PRIMO USER MANAGEMENT SERVICE" : http://localhost:8081/api/auth/getOffers
Looks like it's related to ribbon or hystrix even if i didn't have both dependencies installed.
Did i miss something anywhere ?

... 55 common frames omitted

There are tow ways to solve this issue.
One:
Add a configuration in application:
#RibbonClients(defaultConfiguration = RibbonEurekaClientConfig.class)
Add a file RibbonEurekaClientConfig.java:
public class RibbonEurekaClientConfig {
#Bean
public IPing ribbonPing(IClientConfig config) {
return new NIWSDiscoveryPing();
}
#Bean
public IRule ribbonRule(IClientConfig config) {
return new AvailabilityFilteringRule();
}
#Autowired
DiscoveryClient discoveryClient;
#Bean
public ServerList<Server> getServerList(IClientConfig config) {
return new ServerList<Server>() {
#Override
public List<Server> getInitialListOfServers() {
return new ArrayList<>();
}
#Override
public List<Server> getUpdatedListOfServers() {
List<Server> serverList = new ArrayList<>();
List<ServiceInstance> list = discoveryClient.getInstances(config.getClientName());
for (ServiceInstance instance : list) {
serverList.add(new Server(instance.getHost(), instance.getPort()));
}
return serverList;
}
};
}
}
Two:
Add a configuration in application:
#RibbonClients(defaultConfiguration = RibbonEurekaClientConfig.class)
Add a file RibbonEurekaClientConfig.java:
public class RibbonEurekaClientConfig {
#Bean
public IPing ribbonPing(IClientConfig config) {
return new NIWSDiscoveryPing();
}
#Bean
public IRule ribbonRule(IClientConfig config) {
return new AvailabilityFilteringRule();
}
/*
ribbon:
NIWSServerListClassName: com.netflix.niws.loadbalancer.DiscoveryEnabledNIWSServerList
*/
#Bean
public ServerList<Server> getServerList(IClientConfig config) {
DynamicServerListLoadBalancer<Server> serverDynamicServerListLoadBalancer = new DynamicServerListLoadBalancer<>();
serverDynamicServerListLoadBalancer.initWithNiwsConfig(config);
return serverDynamicServerListLoadBalancer.getServerListImpl();
}
}
Add config in application.yml:
ribbon:
NIWSServerListClassName: com.netflix.niws.loadbalancer.DiscoveryEnabledNIWSServerList

How to fix ZuulException: Forwarding Error

Everything is running on Docker with Kubernetes in Minikube. When I want to connect with my other service (Track service) I am facing a ZuulException exception like below. There are 6 services running. All other services connect succesfully.
Please see the log trace from zuul gateway here:

I am not using Eureka, since Kubernetes has also a discovery service.
When I run everything just on my computer with Eureka I sometimes get the same error. Sometimes it is working and sometimes it isn't..
Now using Kubernetes restarting won't help :') Somebody ideas?

Spring Boot Zuul - Hystrix short-circuited is OPEN

we have some spring boot based microservices sitting behind the spring zuul gateway. At the moment we do some performance testing. We fire up 60 calls distributed over 8 seconds and the only reponses we get is "500 - Internal Server Error" with message "SHORTCIRCUITED"
We don't use spring hystrix in any of the services, but we know that all calls made by zuul are wrapped by hystrix so we tried to configure it in our gateway but nothing helped.
Here is our gateway application.yml (coming from a spring cloud config server):
server:
port: 4444
ribbon:
readtimeout: 5000
sockettimeout: 5000
MaxTotalConnections: 10000
MaxConnectionsPerHost: 10000
MaxTotalHttpConnections: 10000
MaxAutoRetries: 5
MaxAutoRetriesNextServer: 5
# https://github.com/spring-cloud/spring-cloud-netflix/issues/2069
zuul:
host:
maxTotalConnections: 10000
maxPerRouteConnections: 10000
ribbon:
eager-load:
enabled: true
prefix: /api
stripPrefix: false
routes:

serviceId: auth-service
stripPrefix: false
sensitiveHeaders:

The stacktrace from the log of our zuul gateway looks like the following:

The auth-service uses the user-service to request whether an user already exists or not.
Does anyone know how to fix the problem can provide any other useful hints for configuring hystrix in zuul?
Thanks!

In Zuul, hystrix is enabled and can not be disabled.
"SHORTCIRCUITED" can be opened by timeout or exception. Before performance test first, do basic test first.

api-gateway with Spring cloud with zuul and consul for service discovery

I am trying to create a small API-gateway which employs Spring-cloud with Zuul as proxy and consul as service discovery.
Following is my bootstrap.properties:-
spring.application.name=APIGateway
spring.cloud.consul.config.enabled=true
spring.cloud.consul.config.host=localhost
spring.cloud.consul.config.port=8500
server.port=8084
security.basic.enable=false
management.security.enabled=false
spring.cloud.consul.discovery.fail-fast=true
ribbon.ConnectTimeout=30000
ribbon.ReadTimeout=30000
ribbon.eureka.enabled=false
ribbon.consul.enabled=true
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=60000
application.properties:-
zuul.routes.notificationservice.serviceId=notification-service
zuul.routes.tradeservice.serviceId=trade-data-service
zuul.routes.refdataservice.serviceId=ref-data-service
zuul.routes.notificationservice.path=/notificationservice/**
zuul.routes.tradeservice.path=/tradeservice/**
zuul.routes.refdataservice.path=/refdataservice/**
zuul.host.socket-timeout-millis=30000
My Java App:-
#SpringBootApplication
#EnableDiscoveryClient
#EnableZuulProxy
public class MetallicaZuulServiceApplication {
public static void main(String[] args) {
SpringApplication.run(MetallicaZuulServiceApplication.class, args);
}
}
When I run my microservice and gateway, I can see that my consul has both of them registered with it. However, when I request one of my micro services (Ex:- http://localhost:8084/refdataservice) I get a ZuulException: Forwarding Error.
Am I missing something? What could be the reason for same?
