I can’t connect to Unity Services in the Editor.
It has been for days ago… I finally upgrade from 2019.2.16f1 to 2019.3.4f1 but the error persist (cache cleaned).
The error is “Uncaught SyntaxError: Unexpected end of input”.
The console by now don’t show any error.
Suggestions will be appreciated 
I can continue publishing changes.
When I click on Show DevTools:
In Console I only see the error → Uncaught SyntaxError: Unexpected end of input (unityeditor-cloud-hub.js:38).
