Why would I get `504 gateway time-out nginx/1.12.21` error

For Looker-hosted instances: Your web browser talks to a load balancer which forwards the traffic onto nginx reverse proxy servers. Nginx then forwards the traffic to the appropriate looker. That error message means that nginx didn't get a response from Looker in a timely manner.

In short, Looker was/is down. Logs should help us understand the root cause - if your Looker deployment is hosted by Looker, please open a Looker support request for assistance.
