I need to implement OTA, Not able to download file from azure blob

[ijaznoufal]

_httpClient.DefaultRequestHeaders.Add("x-ms-blob-type", "BlockBlob");
HttpResponseMessage response = _httpClient.Get("https://xdatas.blob.core.windows.net/ota/test.pe");
response.EnsureSuccessStatusCode();
var responseBody = response.Content.ReadAsString();

for _httpClient.HttpsAuthentCert = new X509Certificate()// iam using same from https://github.com/BWalti/nf-ssl/blob/main/nf-ssl/Resources/AzureRootCerts.pem

but this is the error iam getting
Issue : An unhandled exception of type 'System.Net.Http.HttpRequestException' occurred in System.Net.Http.dll
