body: <p><a href="https://i.stack.imgur.com/Y12YS.jpg" rel="noreferrer">DEFAULT PROJECT IN VS 2017</a>
  I have created a new Asp.net Core web application in vs 2017 community and published it on a FTP hosting, but when I submit a form (login or user creation) I get this error:</p>
  
  <blockquote>
    <p>Microsoft.AspNetCore.Antiforgery.Internal.DefaultAntiforgery[7]
          An exception was thrown while deserializing the token. System.InvalidOperationException: The antiforgery token could not be
    decrypted. ---> System.Security.Cryptography.CryptographicException:
    The key {...} was not found in the key ring.</p>
  </blockquote>
  
  <p>What do I need to do to make it work? thanks.</p>
