BLOCKER ISSUE: After reopening browser the registered HttpClient refers to wrong base address

[ManrajPatel]

I am developing Blazor Web App with Duende Identity Server. In my Blazor (server) app I am registering HttpClient for my CustomerService using following statement:

services.AddHttpClient<CustomerService>("customer", o => o.BaseAddress = new("https://apiservice"));

Info: CustomerService calls my Api (https://apiservice/) controller action methods to fetch data from database. CustomerService class is implemented in Blazor.Client.

In my Blazor.Client app I have implemented custom authentication state provider BffAuthenticationStateProvider (implementes AuthenticationStateProvider) that uses Duende.Bff to fetch user claims. Following is the code to register HttpClient for this custom Authentication state provider:

builder.Services.AddHttpClient<BffAuthenticationStateProvider>("backend", client => client.BaseAddress = new Uri(builder.HostEnvironment.BaseAddress));

Now ideally when I call any CustomerService method, the injected HttpClient should refer https://apiservice/ as base address and it does work when I run the app for the first time.

ISSUE: But if I close and reopen my browser and try to call the same CustomerService method, the injected HttpClient considers builder.HostEnvironment.BaseAddress as base address and that results in an error because the URL is having a wrong base address.

Can someone please explain what is causing above behavior and how this can be resolved?
