    On my development box I'm getting the following exception in the logs multiple times a day. I've been getting them for a while, but nothing on the site breaks so I never logged it.

    But in just under a 5 hour time span yesterday, this error was logged 20 times in my development environment. Here's one of the log entries (they're all the same stack trace and exception):

    Hi,

    We've just upgraded a site from 8.0 to 8.2 and are getting this error when we try to login to backend. Can you post suggested solutions here please..

    Thank you,

    Hello,

    Are you using load balancing environment? One possible reason for the exception might be if it fails to decrypt the authentication request between the two servers in load balancing. If you are in NLB,

    You can double check the machine key for both application and replace it with a new one(identical on all nodes).

    I would like to suggest to enable temporarily the additional logging as described here: http://docs.sitefinity.com/administration-ensure-content-consistency-on-all-nodes#-troubleshooting-nbsp-


    In order to troubleshoot this issue I would like to kindly ask you to set a copy of your project locally and check whether this issue can be replicated.

    In case everything is working properly on your local machine I would like to ask you to check whether your environment is configured according following documentation article. There is a PowerShell script available that you can execute to ensure that all features needed from Sitefinity are enabled.

    Configuring the IIS to host Sitefinity projects
