You should not specify the version yourself, it will be resolved automatically as long as you have vaadin-bom in your dependencyManagement. When I use Vaadin 14.1.26 then it will take flow-server-mode-production-mode:2.1.9. I assume the version 3.0.6 is used for Vaadin 15, or even Vaadin 16.

The code examples in the [documentation]
(https://vaadin.com/docs/v14/flow/production/tutorial-production-mode-basic.html) for productionmode also show no defining the version.
