Here is code I Wrote:

{
    public class WalletWrapper
    {
        private Config _config;
        private Wallet wallet;

        public WalletWrapper(Config config)
        {
            _config = config;
            wallet = new Wallet(baseUrl: config.baseUrl, apiKey: config.apiKey, apiSecret: config.secretKey);
        }

        public async Task<string> GetSystemStatus()
        {
            Console.WriteLine(wallet);
            return await wallet.SystemStatus();
        } 
    }
}

and Porgram.cs:

using binance_api_consumer.config;
using binance_api_consumer.wallet;
using Binance.Spot;

var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();

var config = new ConfigReader().config;

app.MapGet("/", () => "Welcome!");
app.MapGet("/config", () => config);

var walletWrapper = new WalletWrapper(config);

var func = async () => {
    string s = await walletWrapper.GetSystemStatus();
    Console.WriteLine(s);
    return s;
};

app.MapGet("/wallet", () => func());

app.Run();

Still unable to reproduce.

Can you try to reproduce the issue in it's simplest form as below?

using Binance.Spot;

var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();

app.MapGet("/wallet", async () => {
    Wallet wallet = new Wallet(baseUrl: "https://api.binance.com", apiKey: null, apiSecret: null);
    string s = await wallet.SystemStatus();
    return s;
});

app.Run();

I tried and got response below: {"status":0,"msg":"normal"}

Thanks, I believe it was on my side then. But not sure what :/

EDIT: also I used testnet API, can be this a problem? So I tried on testnet API (https://testnet.binance.vision) and got an error

[tantialex]

The SystemStatus endpoint is /sapi/v1/system/status, which is not supported by the SPOT Testnet, only /api/* endpoints are supported.

Will improve the exception thrown to provide more context regarding the response from the server.
