Backend log shows nothing.

Couldn't reproduce. I synced nginx SSL session with sabis session duration and prolonged it to 20min. This should be sufficient between subsequent measurments. Maybe that's it. Raise the issue again, if it still occours during real measurement sessions.

It reoccured and it looks like that the backend token is just invalid. while the frontend session may stay a little longer, the uses backend token as been issued at login time. from then 20 minutes valid. It looks like that we forgot a renewal process or we need to extend the backend tokens TTL.
