I’m creating a quarkus api with postgres and Keycloak and uploading it to containers.
I am first uploading the keycloak and postgres containers, after uploading I configure keycloak to authenticate my Api endpoints and then I enter the OIDC settings in my application.properties file and upload the application container.
The application container goes up but does not connect with the keycloak and returns the following:

I tried to upload the containers with Docker Compose all together, separately, I tried to configure the OIDC in another way but without success.
