My website has no data!?
If data is showing up in Mongo, but the Website appears blank.
Check your connection strings.
Visit yourwebsite/pebble, eg add /pebble to the end of your website and see if any data is coming back.
Check the date and time of your dexcom. Often, people have the incorrect year set on the Dexcom. The website only shows data from the last two days, so make sure that the Dexcom has the current date and time.
Check that the time on each of your systems matches within a few minutes of each other: Dexcom & Mongolabs & Azure.
