Trouble with Dependency Injection of HttpClient in .NET 6 causing SocketException
I'm updating my dependencies and I've been struggling with this for a few days now and could really use some help. I'm working on a personal project and Hey everyone, I'm running into an issue that's driving me crazy. I'm working with a `SocketException` when trying to use `HttpClient` via dependency injection in my ASP.NET Core 6 application. The exception states `No connection could be made because the target machine actively refused it`. This happens intermittently, and I suspect it may be related to the way I'm configuring the `HttpClient`. I've registered the `HttpClient` in the `Startup.cs` file like this: ```csharp public void ConfigureServices(IServiceCollection services) { services.AddHttpClient<IMyService, MyService>(client => { client.BaseAddress = new Uri("https://api.example.com"); }); } ``` In my service implementation, Iām using it as follows: ```csharp public class MyService : IMyService { private readonly HttpClient _httpClient; public MyService(HttpClient httpClient) { _httpClient = httpClient; } public async Task<string> GetDataAsync() { var response = await _httpClient.GetAsync("/data"); response.EnsureSuccessStatusCode(); return await response.Content.ReadAsStringAsync(); } } ``` I have verified that the API endpoint is reachable outside of my application (e.g., using Postman), and it does respond correctly. What makes this more puzzling is that the behavior doesn't occur consistently; sometimes, the request goes through as expected, and other times, I get the `SocketException`. I've also tried using a named client with `services.AddHttpClient("MyNamedClient", client => ...` but encountered the same scenario. Any insights into why this might be happening or how I can troubleshoot this further would be greatly appreciated. Has anyone else encountered this? Is there a better approach? I'm working with C# in a Docker container on Linux.
