Connection failed Code 2460.

Describe the bug Hello I'm using the dotnet core version of the speech sdk. Sample code from offical doc:

static async Task SynthesizeAudioAsync() 
{
    var config = SpeechConfig.FromSubscription("YourSubscriptionKey", "YourServiceRegion");
    using var synthesizer = new SpeechSynthesizer(config, null);

    var result = await synthesizer.SpeakTextAsync("Getting the response as an in-memory stream.");
    using var stream = AudioDataStream.FromResult(result);
}

this code works perfectly in windows / Ubuntu(vm from azure), but cannot work in Archlinux. here is the error:

Connection failed (no connection to the remote host). Internal error: 1. Error details: 2460. Please check network connection, firewall setting, and the region name used to create speech factory. USP state: 2. Received audio size: 0bytes.

the network environment is same as the windows so I don't think there are any network failure existing. and I haven't set any firewall yet.

here are some sys-info:

$ pacman -F libssl.so.1.0.0
core/openssl-1.0 1.0.2.u-1 [installed]

You probably need to set SSL_CERT_DIR or SSL_CERT_FILE to indicate where SSL certificates are located on Arch Linux. See https://docs.microsoft.com/en-us/azure/cognitive-services/speech-service/how-to-configure-openssl-linux for instructions.
