If you faces it during online payment then check these url.

It may causes for redirection route. Let's say, your sites is https but redirection url is http

You may set www prefix mandatory. ping these

Note: I had experienced similar issue during setup "PAYPAL EXPRESS PAYMENT PLUGIN".

Basically you have to configure tag <machineKey> in web.config.

Example:

<machineKey validationKey="F86B41324A2AA71D57C057E1E330B7480E64FB6E3604BCCD89A5578253A71F5D83CAA0CFC350C59B9D9A93128ABA9256E2BCC387115574B4A3558E5E4419302B" decryptionKey="20BA759092E7DB25F464189CB9CDE07A7EC48A28F362C4114657E11BAC4177AA" validation="SHA1" decryption="AES" />
