Disabled Instances keep "hanging" in Gateway

Question

Hi all,

we are currently sharing a Yuuvis environment between demonstration/live testing and development. Whenever I need to locally debug a backend microservice, I connect it via dev proxy after deactivating the instance deployed on remote.

For this purpose, I am using the endpoint manage/apps/<APP_NAME>/instances/, setting the instance count to 0.

I noticed, that the remote instance will be shown as "offline", but the gateway keeps directing requests there in round-robin. This results in every second request failing with 503. This behavior will occurr for another 5 minutes, the disabled instance will then disappear and everything will be normal again.

Is this behavior expected? Am I doing something wrong? Really appreciating any clues.

Best regards,

Felix

Hello Felix,

this is a configuration of the spring boot eureka component. Please see here for a possible solution:
