Steps to reproduce the issue:
- Solution was genered by the abp suite and initially looked like this:
- We have a requirement to use chat, so I mannually added a MyProject.Web project to host singalR
  - This new project is called MyProject.Web but it does not host any web pages / ui
  - Now the solution looks like this:
  - These are the dependecies I'm using for the MyProject.Web Module [DependsOn( typeof(AbpAutofacModule), typeof(MyProjectHttpApiClientModule), typeof(MyProjectApplicationContractsModule), typeof(AbpHttpClientIdentityModelModule), typeof(AbpFeatureManagementWebModule), typeof(AbpAspNetCoreSerilogModule), typeof(AbpAspNetCoreSignalRModule), typeof(AbpEventBusRabbitMqModule) )]
  - I added the following to Configure Services: context.Services.AddHttpClientProxies( typeof(MyProjectApplicationContractsModule).Assembly );
    - I added authentication like this:
    - OnAppInitialization is configured like this:
    - The chat hub is trying to call the MyProject.HttpApi.Host userAppService using a Dynamic Api Client
    - Using a normal HttpClient and setting the Authorization header works normally, but using the IHttpClientProxy client fails with error: Authorization failed! Given policy has not granted.
  - Comments We have it configured this way because we are using other tools to scale and load balace the services I would like to use a IHttpClientProxy for my SignalR hub to call the services from my HttpApi.Host project. As I understand it is supposed to intercept the HttpContext and set the authorization header on the client. Is there some configuration that I am missing?
