Elma reveals: "There is no OWIN authentication manager associated with the request."

My elmah logs show this error. This does not happen with every request. This happens intermittently. MVC 5.2, Web API 2.2, ASP.NET Identity 2, and Azure are my environment. update: Here is my Startup.cs,

OAuthOptions = new OAuthAuthorizationServerOptions() { AllowInsecureHttp = true, TokenEndpointPath = new PathString("/token"), AccessTokenExpireTimeSpan = TimeSpan.FromMinutes(settings.AccessTokenExpireTimeSpanInMinutes), Provider = new MyAuthorizationServerProvider(), RefreshTokenProvider = new MyRefreshTokenProvider() }; // Web API configuration and services // Configure Web API to use only bearer token authentication. GlobalConfiguration.Configuration.SuppressDefaultHostAuthentication(); GlobalConfiguration.Configuration.Filters.Add(new HostAuthenticationFilter(OAuthOptions.AuthenticationType)); app.UseOAuthAuthorizationServer(OAuthOptions); app.UseOAuthBearerAuthentication(OAuthBearerOptions); GlobalConfiguration.Configuration.SuppressDefaultHostAuthentication(); GlobalConfiguration.Configuration.Filters.Add(new HostAuthenticationFilter(OAuthOptions.AuthenticationType));

Checked this. There is no OWIN authentication manager associated with the request , but it does not work.

I was able to play it on my pc. Just restart the application domain and send the request to api. I will get the above error. After that, everything will be fine. Here is the stacktrace from my local machine,

I do not use the OAuth server, which is available in the SPA template.

 config.SuppressDefaultHostAuthentication(); config.Filters.Add(new HostAuthenticationFilter(Startup.OAuthOptions.AuthenticationType));

The fix is ​​to use Microsoft.AspNet.WebApi.Owin (UseOwinMethod). This also fixed Server cannot append header after HTTP headers have been sent. . I found an error in this package that could also be work around. Why does MessageHandler execute an MVC request? Related http://katanaproject.codeplex.com/discussions/540202

I use a third-party basic authentication Thinktecture.IdentityModel.Owin.BasicAuthentication ( Thinktecture.IdentityModel.Owin.BasicAuthentication ) and get the same error as the OP. I always had a link to Microsoft.Owin.Host.SystemWeb .

In the end, I skipped these lines in my App_Start code:

 config.SupressDefaultHostAuthentication(); config.Filters.Add( new HostAuthenticationFilter("") );

After I deleted both lines, it worked as intended.

How are you trying to access the owin context in your API? In WebApi you should use Request.GetOwinContext () (unlike HttpContext.GetOwinContext (), which you would use in MVC).
