title: The anti forgery token could not be decrypted? [Cant get rid of this strange error]
body: <p>I have developed a web application in Asp.Net MVC using c# language with code first approach, the application is deployed in actual web server and functioning pretty much well except this error that shows up few times.</p>
  
  <pre><code>The anti-forgery token could not be decrypted. If this application is hosted by a Web Farm or cluster, ensure that all machines are running the same version of ASP.NET Web Pages and that the &lt;machineKey&gt; configuration specifies explicit encryption and validation keys. AutoGenerate cannot be used in a cluster
  </code></pre>
  
  <p>The reason that i called this error strange is that it is unexpected, It means that it occurs sometimes but not always. </p>
  
  <p>For example, when i try to log in to a single account of my application (For eg to Account of John) from two different computers then I may or may not get this error.</p>
  
  <p>Now this unexpected nature of this error can't allow me to figure out where the actual problem is?</p>
  
  <p>Kindly provide your suggestions or comments that could help me figure out this issue.</p>
  
  <p>Thanks in advance.</p>
