Fabric (Crashlytics) for unity 2017

Somebody installed carashlytics on Unity 2017?
I can’t login… And install the plugins.

Getting this error when try to login:

[Fabric] An exception has occured; Error writing request: The authentication or decryption has failed.
Fabric.Internal.Editor.Utils:Warn(String, Object) (at Assets/Fabric/Editor/FabricUtils.cs:18)
Fabric.Internal.Editor.Controller.PluginController:OnLoginError(Exception, Action1) (at Assets/Fabric/Editor/GUI/Controller/PluginController.cs:537) Fabric.Internal.Editor.Controller.c__AnonStorey6:<>m__0(Exception) (at Assets/Fabric/Editor/GUI/Controller/PluginController.cs:564) Fabric.Internal.Editor.Detail.c__Iterator0:MoveNext() (at Assets/Fabric/Editor/GUI/Detail/AsyncTaskRunner.cs:106) Fabric.Internal.Editor.Detail.AsyncTaskRunner1:Update() (at Assets/Fabric/Editor/GUI/Detail/AsyncTaskRunner.cs:143)

Also debug the code. The error start to appear after this:

namespace Fabric.Internal.Editor.Net.OAuth

public sealed class Client

	public Token Get (string username, string password)
		HttpWebRequest request = PrepareRequest (
			                         URI + TokenEndpoint + DefaultScopeQuery

		using (Stream stream = request.GetRequestStream ()) {
			string entity = ComposeEntity (username, password, AppId, Secret);
			byte[] bytes = Encoding.UTF8.GetBytes (entity.ToString ()); 
			stream.Write (bytes, 0, bytes.Length);  // <------ here

		using (Stream stream = request.GetResponse ().GetResponseStream ()) {
			return fromStream (stream);

I found a temporary fix:

  1. Go to Fabric/Editor/GUI/Net/OAuth/Client.cs

  2. Insert this “ServicePointManager.ServerCertificateValidationCallback += (o, certificate, chain, errors) => true;” line of code to the top of the ‘PrepareRequest’ method

  3. Go to Fabric/Editor/Update/TimeoutWebClient.cs

  4. Insert same line as in point (2) to the top of the ‘GetWebRequest’ method

  5. Profit

Optional: use something like a ‘#warning Temporary quick fix!’ so that you don’t leave it there.
