  hi

  System.Security.Cryptography.CryptographicException: The system cannot find the file specified. at System.Security.Cryptography.CngKey.Open(String keyName, CngProvider provider, CngKeyOpenOptions openOptions)

  Please check and make sure the authserver.pfx file exists on your azure.

  public override void PreConfigureServices(ServiceConfigurationContext context)
  {
      var hostingEnvironment = context.Services.GetHostingEnvironment();
      var configuration = context.Services.GetConfiguration();
  
      context.Services.PreConfigure<AbpMvcDataAnnotationsLocalizationOptions>(options =>
      {
          options.AddAssemblyResource(
              typeof(StatAlertResource),
              typeof(StatAlertDomainModule).Assembly,
              typeof(StatAlertDomainSharedModule).Assembly,
              typeof(StatAlertApplicationModule).Assembly,
              typeof(StatAlertApplicationContractsModule).Assembly,
              typeof(StatAlertWebModule).Assembly
          );
      });
  
      PreConfigure<OpenIddictBuilder>(builder =>
      {
          builder.AddValidation(options =>
          {
              options.AddAudiences("StatAlert");
              options.UseLocalServer();
              options.UseAspNetCore();
          });
      });
  
      if (!hostingEnvironment.IsDevelopment())
      {
          PreConfigure<AbpOpenIddictAspNetCoreOptions>(options =>
          {
              options.AddDevelopmentEncryptionAndSigningCertificate = false;
          });
  
          PreConfigure<OpenIddictServerBuilder>(builder =>
          {
              builder.AddSigningCertificate(GetSigningCertificate(hostingEnvironment, configuration));
              builder.AddEncryptionCertificate(GetSigningCertificate(hostingEnvironment, configuration));
              builder.SetIssuer(new Uri(configuration["AuthServer:Authority"]));
          });
      }
  }
  

  This is the code in the GetSigningCertificate (minus the line that defines the actual key) var file = Path.Combine(hostingEnv.ContentRootPath, fileName);

      if (!File.Exists(file))
      {
          throw new FileNotFoundException($"Signing Certificate couldn't found: {file}");
      }
  
      return new X509Certificate2(file, passPhrase);
  

  NOTICE that the message if the file doesn't exist is not the message received in the error.

  hi

  Can you try X509KeyStorageFlags?

  return new X509Certificate2(file, passPhrase, X509KeyStorageFlags.MachineKeySet);
