Exception when trying to connect Eureka Server with Config Server in Docker Compose ("Connection refused")

co flag

I have created a Eureka Server and a Config Server and I am trying to get the Euketa Server properties that are in the Config.

I'm trying to dockerize these two services and for that I created a docker-compose.yml, but when I run the containers the Eureka Server is throwing a "Connection refused" exception. The config-server is starting normally, but the eureka server is throwing an exception.

When I run both services through the IDE they work normally, but not through Docker.

Does anyone know what the problem could be?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
