Unable to start with docker-compose due to connection refused

[vijamesDD]

Hi, I'm trying to run this simple tasklist locally using the docker compose instructions and I get a connectivity error between the tasklist worker and zeebe broker.

Using the latest main branch, when I run this docker compose command
docker-compose --profile in-memory up

I get this error

Note that the zeebe broker seems to have started up fine

...

Is anyone able to provide suggestions as to how to fix? I'm using the docker compose file from this repository https://github.com/camunda-community-hub/zeebe-simple-tasklist/blob/main/docker/docker-compose.yml

Perhaps I am missing some other setup that is required? Thanks very much

@vijamesDD thank you for reporting. 👍

It is working for me. 🤔
Please share the complete console output from Docker and details about your environment.
