Thanks @Eiji.

Keep in mind that the ownership timeout is controlled by the :ownership_timeout configuration. I think we improve the error message for it in more recent versions as well.

@CastLouis: so it’s a sub application in umbrella project. Make sure that other application does not override it’s configuration, for example:
File: umbralla_app/apps/a:

config :my_app, :something, true

could be overwritten by umbreall_app/apss/b:

config :my_app, :something, false

Please also update your post with proper markdown:

Please use this syntax:
```elixir
# your code goes here …
