Login page forwards to webcomponents-loader.js

Hi guys,

first of all what I am trying is, to have a normal website and a login page which should be accessible through the direct link ‘http://topleveldomain.com/login’, after a successful authentication it should take me to another view/page (‘secured’ area).

Just for the record, I am very new to the Vaadin framework, so forgive me my inexperience and maybe from your view stupid questions.

I followed this tutorial https://vaadin.com/learn/tutorials/java-web-app/login-screen. And if you need some code sequences from my project to
help me better, tell me and then I will provide those.

So far,
