Have just put a locally running V13 site live and can't get it running. The back office is fine, the Preview and Live front end pages revert to the default 404 page (rather than the one set in appsettings). In the logs there is the following error:-
Microsoft.AspNetCore.Antiforgery.AntiforgeryValidationException: The antiforgery token could not be decrypted.
---> System.Security.Cryptography.CryptographicException: The key {f1ae5c12-0cf6-4f78-863f-bb3cd0401206} was not found in the key ring. For more information go to

I've cleared all cookies and restarted but no improvement.
Anyone any clues as to what I might have missed?
Thanks.
