@nguyentuycuong @AlecSK @mudasir-alp77 The BlazingPizza.Server project uses IdentityServer for authentication users. As part of the IdentityServer configuration - its needs a certificate to sign the tokens. In development mode, Identity Server allows you to not use a certificate but just use a key called Development. This can be seen in appsettings.Development.json file. Here is the code:

{
  "Logging": {
    "LogLevel": {
      "Default": "Debug",
      "System": "Information",
      "Microsoft": "Information"
    }
  },
  "IdentityServer": {
    "Key": {
      "Type": "Development"
    }
  }
}

When you use Visual Studio and run the application, VS sets an environment variable named "ASPNETCORE_ENVIRONMENT" to Development. If you do the deployment to your server other than a local development - you will need to make sure to provide a valid certificate to Identity Server. Take a look at this article from @csharpfritz - https://devblogs.microsoft.com/aspnet/asp-net-core-authentication-with-identityserver4/. Read through section Adding IdentityServer4. That explains how to provide a certificate for signing the tokens.

Hope this helps.
