Endpoints won't load in Spring Admin Frontend 2.0

[srep2512]

Hi,

I've tried to make use of the endpoints in spring boot 2.0 and changed my properties file according to your doc.
management.endpoints.web.exposure.include=* management.endpoint.info.enabled=true management.endpoint.loggers.enabled=true

The problem is that it won't load the actual data into the frontend of the admin app.
If I run the route directly it shows all the data.

Any Error in the browser's console?

[srep2512]

sadly no errors in console of the browser. In the network tab it shows the following link:
http://localhost:50000/instances/<instance_id>/actuator/loggers
my client runs on http://ipaddress:3000.

For the client i used in gradle
compile('de.codecentric:spring-boot-admin-starter-client:2.0.0-SNAPSHOT')
and for the server
compile('de.codecentric:spring-boot-admin-server:2.0.0-SNAPSHOT')
compile('de.codecentric:spring-boot-admin-server-ui:2.0.0-SNAPSHOT')

It would be sad to write my own client to fetch these ressources, because i like the style of your frontend so far

after update to spring-boot 2.0.1 applications are not loaded any more (i'm using Eureka, not spring-boot-admin-client).

Here is the log:

@srep2512 if you're using 2.0.0 snapshot of boot-admin-server, ensure you have 5.0.5 version of spring-framework dependencies. This helped me to solve registration problem (although "broken pipe" error still pollutes logs)

[srep2512]

@n0mer thanks for the hint! To add the dependencies for spring with Version 5.0.5 really did the trick!

sounds like this issue is solved.
