I am getting an Event Viewer error every two minutes on my IIS instance

Event code: 3012 

Event message: An error occurred processing a web or script resource request. The resource identifier failed to decrypt. 

Exception type: CryptographicException 

    Exception message: Error occurred during a cryptographic operation.

   at System.Web.Security.Cryptography.HomogenizingCryptoServiceWrapper.HomogenizeErrors(Func`2 func, Byte[] input)

   at System.Web.UI.Page.DecryptString(String s, Purpose purpose)

   at System.Web.Handlers.AssemblyResourceLoader.System.Web.IHttpHandler.ProcessRequest(HttpContext context)

 

This is a fully updated DNN community site.  I am fearful I can't fix the issue and the site will crash.  Any thoughts?

I have entered those settings into host and all of our child portals (130) are all set to host as the SMTP mode.  The SMTP server is JangoSMTP.

 The errors persiste even after re-entering
