Prefect Community

I enabled slack notification on prefect flows, I receive notification when the state changes which is perfectly fine, however the link there points to localhost:8080 how do I properly link so that when some clicks they can go to that task run ? thanks
```<http://localhost:8080/default/task-run/bcb01c03-6507-40c3-8c31-c2a0a37a9868>```

how did you start your Server? you can set the Server host in your config.toml and use the --expose flag when starting Server to ensure it will be exposed to all services

I started the server with expose flag and I can access the UI at `<http://my_host:8080>`

it is only the links in the slack notifications that are pointing to `localhost:8080` which variable/parameter I need to set ?

in that case maybe you can adjust it directly in your state handler?

I think I had a similiar problem and solved it by setting the environment variable `PREFECT__SERVER__UI__HOST`

If you look at the code, the `base_url` in the `Client` `get_cloud_url` method takes `prefect.config.server.ui.endpoint` when not using Prefect Cloud, and the slack formatter calls that method, so the environment variable I mentioned sounds correct.
