TLS alert: 'HandshakeFailure'

[LincolnDing]

Hi,this is code piece

public async Task GetAnswer(string text)
{

        string answer = "";

        OpenAIService service = new OpenAIService(new OpenAiOptions() { ApiKey = OpenAIToken });

        CompletionCreateRequest createRequest = new CompletionCreateRequest()
        {

            Prompt = text,
            Temperature = 0.3f,
            MaxTokens = 1000
        };

        var res = await service.Completions.CreateCompletion(createRequest, Models.TextDavinciV3);

        if (res.Successful)
        {
            answer = res.Choices.FirstOrDefault().Text;

        }
        return answer;

    }

When I am running it on my server, it returns an error : Authentication failed because the remote party sent a TLS alert: 'HandshakeFailure'.

When I am running it on local pc,it runs ok.
I have checked the setting of TLS between server and local pc, they are the same each other.
btw,I can get normally response from openai.com’s playground on server.

thank you.

It seems like an issue with your environment. I will move this issue into discussions and if you can share more details about the error we may help you.

hi there:
I seem to have the same problem,
system : Windows server 2012 R2 x64; IIS: 8.5; TLS: 1.2
throw an exception:"The SSL connection could not be established, see inner exception."

Do you have any more detail, a stack trace maybe?

I will try to add ignore Certificate Errors option to the library.

[kayhantolga]

Could you try this code on your server, if it works I will add an option for ignoring the cert error.

var clientHandler = new HttpClientHandler();
clientHandler.ServerCertificateCustomValidationCallback = (sender, cert, chain, sslPolicyErrors) => true;
var client = new HttpClient(clientHandler);

var options = Options.Create<OpenAiOptions>(new OpenAiOptions()
{
    ApiKey =  Environment.GetEnvironmentVariable("MY_OPEN_AI_API_KEY")!
});
var openAIService = new OpenAIService(client, options);

if you were using dependency injection and testing would be hard, just let me know. we can find another way to try

Hi kayhantolga:
thank you for your reply.
unfortunately, this code doesn't work, so I upgraded my operating system. and now it works perfectly.
thank you!
