"502 Bad Gateway" or "Cannot GET /node-red-test/"
Sometimes we can no longer access the Grafana user interface or the Node-RED editor through the public device URL after a deployment (git push resin master). In that case we get a 502 Bad Gateway or Cannot GET /node-red-test/
Note that in most cases this error can be fixed by restarting the nginx container !
so far restarting the nginx container always fixed this issue.
