There is a known bug in Matrix which causes a failed authenticated on Kodi startup. This leads into a not working real-time-monitor. 
Sometimes it can work, sometimes not. We are already investigating why this is happening. It's not reproduceable on all systems.

I'm just guessing, but I bet it's the same issue on your end. You should see a message in the log that the observer isn't able to authenticate (after Kodi startup). A log will tell us more.
