NAV Odata Reference HTTP Error

Hi all,

Recently we've made a migration to a new server with Dynamics Business Central 365.
We have a internal application in c# that uses Odata to Update/Delete information between NAV and c#

When i try to update the service it gives me this error

I also changed some IIS configurations accordind the old server.
Enabled Windows authentication and Enable PRoviders Negotiate and NTLM by this order.

I restarted the server and it worked, but then it stoped.

Also I got this.

With old server i've got no problem

Any help would be apreciated thanks.
