Dear Team,
I’m trying to deploy simple spring-boot zeebe client using docker. But as soon as the application starts, I get connection refused error as below. I have docker compose zeebe broker (simple monitor) already running successfully. Below is the source code I’m using to build the docker containers.
Zeebe broker: zeebe-docker-compose/simple-monitor at master · zeebe-io/zeebe-docker-compose · GitHub
Zeebe springboot client: spring-zeebe/examples/starter at master · zeebe-io/spring-zeebe · GitHub
Note: I’m able to successfully connect to zeebe broker from java client container from this source code in Github:
zeebe-io/zeebe-get-started-java-client
But however I would like to use a spring boot zeebe client. Could you please help.
Below is the error I get:
Error starting ApplicationContext. To display the conditions report re-run your application with ‘debug’ enabled.

I tried this application configuration
zeebe.client.broker.gatewayAddress:127.0.0.1:26500
zeebe.client.security.plaintext:true
or
zeebe.client.broker.contactPoint: 127.0.0.1:26500
but still I get this error:Caused by: io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: /127.0.0.1:26500
Caused by: java.net.ConnectException: Connection refused
Thanks in Advance,
