All of my users including myself have still been experiencing "Error 401 - User not registeredERRORUser is not registered on the reporting server."
The error occurs when trying to download files in the advanced reporting module. We have tried every browser, clearing caches, ect.
An internet browser extension called LastPass was found to be the cause of this issue. The LastPass plugin appears to have altered the CSRF token during the export operation and hence the user was getting 401 user access reporting error
Workaround: Use Firefox or Disable the Plugin
The JS-38127 has been resolved as of JRS 7.9.x.
