IE Error: Unhandled exception occurred: System.FormatException: Unable to deserialize Json to create WorkflowState.

Some, but not all IE users are getting this error.  It does not seem to matter what version of IE they are using and it works OK for all users on all computers with Chrome.  In some cases it will work in IE for different users on the same computer and not for others, even admins are having troubles. We have even compared settings to users who work OK and those who don't. In one case the only difference we found was the "Send IDN Server names". Once it was changed it seemed to work, however upon reboot, it again failed. Then again this setting did not work for other users.

If anyone has any ideas, please let me know.

Thank You

  In this case, a work around was found for those having trouble by either using the fully qualified domain name to the GCE site, or by adding it to the proxy exemptions list. Not sure what is causing this to happen, however, in this case it has been successful.
