I'm working with MAUI to create my App. Sometimes my endpoint throws "503 Service unavailable" on my App while this is reachable on other systems.

HttpClient _client = new HttpClient();
_client.DefaultRequestHeaders.TryAddWithoutValidation("Authorization", _ud.sess_id);

string endpoint= "https://............."

var response = await _client.GetAsync(endpoint);
var r = await response.Content.ReadAsStringAsync();

if (response.StatusCode != System.Net.HttpStatusCode.OK)
{
   await DisplayAlert("Info", r, "OK");
   return;
}

The problem stays for a day on all Android phones, then it works fine for days.

On IOS there is no Problem with the same code.

Server is up and good.

Is this a known Problem and how to solve it?

    generally any 5xx error is a server issue, and you need to debug the code and examine the logs on the server to see what the problem is Commented Jan 23 at 14:58
