We have been trying to setup `concourse 5.0.0` (we already set up `4.2.2`) in our AWS. We have created two instances one is for web and another is for worker. We are able to see the site up and running but we are not able to run our pipeline. we checked the logs and noticed that worker throwing the below error.

```
Workerr.beacon.forward-conn.failed-to-dial","data":{"addr":"127.0.0.1:7777","error":"dial tcp 127.0.0.1:7777: connect: connection refused","network":"tcp","session":"9.1.4"}}

```

We are assuming worker is struggling to connect to `web` instance and wondering if this could be due to missing gdn configuration. Concourse `5.0.0` release included both concourse and gdn binaries. we want to try `--garden-config` file to see if that fixes the problem.

can somebody suggest how do we write garden config file ?
