Semantic Kernel. 'The SSL connection could not be established, see inner exception.'

[GDT48]

I am trying Semantic Kernel with OpenAI in a Muai application. I am able to successfully get a simple prompt response using windows. However running under Android (emulator and local device) I get the error Microsoft.SemanticKernel.HttpOperationException: The SSL connection could not be established, see inner exception.

The following is the relevent code block, complete n Entry. Output goes to Label (Answer).

Error is raised at line:

var response = await kernel.InvokePromptAsync(((Entry)sender).Text);

As mentioned above code runs OK on Windows Machine but not on Android.

    public static IKernelBuilder builder = Kernel.CreateBuilder();
    public static Kernel kernel = builder
             .AddOpenAIChatCompletion("gpt-4o-mini", OpenAI_Key)
            .Build();

private async void Question_Completed(object sender, EventArgs e)
{
if (!string.IsNullOrEmpty(((Entry)sender).Text))
{
try
{
string request = ((Entry)sender).Text;
ActivityIsRunning = true;
var response = await kernel.InvokePromptAsync(((Entry)sender).Text);
Answer.Text += $"You: {((Entry)sender).Text}{Environment.NewLine}AI: {response.ToString()}{Environment.NewLine}{Environment.NewLine}";
((Entry)sender).Text = string.Empty;

        ActivityIsRunning = false;
    }
    catch (Exception)
    {

        throw;
    }

}

}
Full exception as follows:

I have search the internet and AI for a solution but unable to resolve. As I don't have a problem with running on Windows I'm guessing something Android specific but don't know what.

This might be related to #6993 @RogerBarret0

I've also shared a quick workaround for this here: #10082 (comment)

[sophialagerkranspandey]

Thanks @arafattehsin , we have reopened the issue and Roger is looking into the details you provided in #10082 (comment)
