did you make any changes to your flow before this happened?

it looks like a problem with the HUE - notice the `Api Error: Unexpected response status; 404` which is causing node-red to crash and then it is restarted.

Do this, from a terminal window enter  
`sudo systemctl disable nodered.service`  
then  
`node-red-stop`  
then you should be able to start node-red in debug node with  
`node-red --safe`  
this will start the node-red dashboard. go to the Palette manager and get a list of all nodes you are currently using and see what `hue` nodes you are using. You should go to the GitHub page for thise nodes and see if there are any issue that may relate to your issue and maybe a solution.

If you want to get the flow working, disable any `hue` related nodes until you get a fix for the underlining issue
