GenerateEmailConfirmationTokenAsync(user) generates error Encryption Failed - asp.net-core

Question

A call to GenerateEmailConfirmationTokenAsync(user) method returns with the error message Encryption Failed
This is a .Net Core Application with a resource server and an authentication Server.The User Accounts Management is being done on the resource server. When execution gets to
var code = await _userManager.GenerateEmailConfirmationTokenAsync(user);
I get the error message Encryption Failed
Below is the configuration for data protection
var cert = new X509Certificate2(Path.Combine(folderForKeyStore, "teejay.pfx"), "xxxxxxxxxx");
var folderForKeyStore = Configuration["Data:KeyStoreFolderWhichIsBacked:keystore"];
services.AddDataProtection()
.SetApplicationName("Academic Records Management System")
.ProtectKeysWithDpapiNG("CERTIFICATE=Hashid:" + cert.Thumbprint, flags: DpapiNGProtectionDescriptorFlags.None)
.PersistKeysToFileSystem(new DirectoryInfo(folderForKeyStore));
The following is the stack trace
