In a situation like this it is very helpful if you [provide your flow](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506), espically as you say this is just a test.

Also provide  
os platform and release  
versions of NR and node.js

Also where is this button you are pressing?

P.S. having just installed the `Create an HTTP Endpoint` flow on my local machine, when I click the link in your post, the `Hello World` is returned
