Logic Apps - authentication loop in Visual Studio 2015

Question

When adding the "Dynamics365 for operations" connector inside my Logic App flow and try to connect with it i get the following error:

A new window pops up asking for my credentials. Upon entering my credentials the page becomes white with on the top "working..." After a while i get the error Timeout.

I tried the following solutions:

• Starting Visual Studio in admin: had partial success, now i get one setup further into the authentication but i still get into the same authentication loop.
  

• Opening the link in Google Chrome just says
  

  {"Message":"The request is invalid.","ModelState":{"consentInfo":["No consent server information was associated with this request."]}}

• I have added the link to trusted sites on IE.

• Disabled security in the internet options of IE.

Answer 1

after a lot of trial and error i managed to fix it! For some reason i had to disable the "Anonymous Authentication" in the IIS manager in my default web site and enable the "Forms Authentication".
