### Describe the bug

Hi,

I am not able for http client set timeout, however client.Timeout is 120 sec.
I tried direct change timeout, over timeout policy, nothing works.
As soo as I remove .AddServiceDiscovery() from http client setup and user hardcoded url, all works fine
and timeout was accepted.

example:

builder.Services.AddHttpClient("documentprocessingapi",
client =>
{
var url = config.GetValue("Api");
client.BaseAddress = new Uri(url);
client.Timeout = TimeSpan.FromSeconds(2000);
Log.Logger.Information("Set timeout to 120 sec");
})
//.AddPolicyHandler(timeoutPolicy)
.AddServiceDiscovery()
.ConfigurePrimaryHttpMessageHandler(() =>
{
var handler = new HttpClientHandler();
handler.ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAnyServerCertificateValidator;
return handler;
})
.ConfigureHttpClient(client =>
{
client.Timeout = Timeout.InfiniteTimeSpan; // ⏳ Force unlimited timeout at HttpClient level
});

I am getting error:
