Spring-cloud-netflix: Eureka Server is Up. But dashboard is not coming

[duraikutty]

Hi ,

Spring boot 2.1.3.RELEASE
Java 1.8
Spring Cloud version Greenwich.SR1

Eureka server is up. But, I am not able to view the Eureka server dashboard.

[spencergibb]

Please provide details of the problem, including the version of Spring Cloud that you are using. If possible, please provide a test case or sample application that reproduces the problem. This makes it much easier for us to diagnose the problem and to verify that we have fixed it.

What url are you accessing? What is your configuration?

We are not able to view dashboard of eureka server.
Whitelabel Error Page is showing.

[Tataraovoleti]

I m having same issue.
When i access http://localhost:8761/eureka/ getting 404 error

But my remaining services are able to register themselves with eureka registry. The only problem i could see dashboard is not coming up.

[OlgaMaciaszek]

Hello, @duraikutty @Tataraovoleti I have tried recreating the issue against the provided versions of Spring Cloud and Spring Boot and it worked ok for me. Maybe there's sth more you've missed while providing us your setup? In order to verify what is happening, I would suggest to temporarily set the logging level for Spring to DEBUG and check if any more details for the 404 can be found there.

If that does not help, please provide a minimal, complete, verifiable example that reproduces the issue.

[OlgaMaciaszek]

@Tataraovoleti I've recreated this setup (See the eureka-test-2.zip) and I can run it and launch the dashboard without any issues. We will really need either more info from the logs or a demo that reproduces the issue (github repo link or zip) to further verify it.

This happens when using the most recent build (24/6/2019)
Downgrading to previous build versions works i.e. (10/6/2019)

Sounds like a bad jar, try cleaning your maven repo and try again

Hi to all,
I am facing the same issue,
Could any one help me out there.

Resolved [feign.RetryableException: connect timed out executing GET http://currency-exchange-service/currency-exchange/from/USD/to/INR] occured

here, i didn't get why http://currency-exchange-service/currency-exchange/from/USD/to/INR called instead http://localhost:8000/currency-exchange/from/USD/to/INR

[kfrajtak]

If you generate the Spring project using Spring Initializer the dashboard won't open ending in "Whitelabel Error Page".
No need for MVP, just go there and generate it.

[komal3770]

Add this lines in application.properties and error will be gone
