Description

I'm experiencing some unexpected "Access Token not found" errors after upgrading to 1.17.0.

See attached traceback.

What happens is that the NiFi UI seems to work but after a short while the view is redirected to a conflict page (Unable to communicate with NiFi). There are no other problems or evidence of the issue to be found in the logs.
