Frequent "502 Bad Gateway" and "Celery not running" warning when home does load

[benjigreig]

I'm setting up to new boards and putting the current version of the repo on following your docs. I've gotten through the process of getting everything installed and it all seems to be running as intended (based on the instructions).

However after booting the pi, when I log into the intervalometertor local website on the Pi I frequently get 502 errors. If and when I do get the index page I'm generally met with a "Celery not running" warning message.

Not sure how to proceed. Have tried reinstalling from the setup.sh but have the same issue.

Any help trying to debug would be greatly appreciated.
